  • Probing effect of tensor interactions in O-16 via (p, d) reaction

    Ong, H. J.   Tanihata, I.   Tamii, A.   Myo, T.   Ogata, K.   Fukuda, M.   Hirota, K.   Ikeda, K.   Ishikawa, D.   Kawabata, T.   Matsubara, H.   Matsuta, K.   Mihara, M.   Naito, T.   Nishimura, D.   Ogawa, Y.   Okamura, H.   Ozawa, A.   Pang, D. Y.   Sakaguchi, H.   Sekiguchi, K.   Suzuki, T.   Taniguchi, M.   Takashina, M.   Toki, H.   Yasuda, Y.   Yosoi, M.   Zenihiro, J.  

    We have measured the O-16(p,d) reaction using 198-, 295- and 392-MeV proton beams to search for a direct evidence on an effect of the tensor interactions in light nucleus. Differential cross sections of the one-neutron transfer reaction populating the ground states and several low-lying excited states in O-15 were measured. Comparing the ratios of the cross sections for each excited state to the one for the ground state over a wide range of momentum transfer, we found a marked enhancement of the ratio for the positive-parity state(s). The observation is consistent with large components of high-momentum neutrons in the initial ground-state configurations due to the tensor interactions. (C) 2013 Elsevier B.V. All rights reserved.

  • Probing effect of tensor interactions in 16O via (p,?d) reaction

    Ong, H.J.   Tanihata, I.   Tamii, A.   Myo, T.   Ogata, K.   Fukuda, M.   Hirota, K.   Ikeda, K.   Ishikawa, D.   Kawabata, T.   Matsubara, H.   Matsuta, K.   Mihara, M.   Naito, T.   Nishimura, D.   Ogawa, Y.   Okamura, H.   Ozawa, A.   Pang, D.Y.   Sakaguchi, H.   Sekiguchi, K.   Suzuki, T.   Taniguchi, M.   Takashina, M.   Toki, H.   Yasuda, Y.   Yosoi, M.   Zenihiro, J.  

    We have measured the 16O(p, d) reaction using 198-, 295- and 392-MeV proton beams to search for a direct evidence on an effect of the tensor interactions in light nucleus. Differential cross sections of the one-neutron transfer reaction populating the ground states and several low-lying excited states in 15O were measured. Comparing the ratios of the cross sections for each excited state to the one for the ground state over a wide range of momentum transfer, we found a marked enhancement of the ratio for the positive-parity state(s). The observation is consistent with large components of high-momentum neutrons in the initial ground-state configurations due to the tensor interactions. [All rights reserved Elsevier].

  • Retorno econômico dos investimentos em P&D na citricultura paulista

    Figueiredo, Margarida Garcia de   Barros, Alexandre Lahóz Mendonça de   Conceição, Junia Cristina Peres Rodrigues da  

    The objective of this study was to assess the economic return from R&D investments in the citrus sector in São Paulo state, Brazil. Brazilaccounts for 80% of the total frozen concentrate orange juice (FCOJ) traded in the international market, and São Paulo state is responsible for 98% of Brazilian FCOJ exports. The Tornqüist Index Method was used to estimate the Total Factor Productivity (TFP) for the citrus industry, in order to compare the outcomes with and without citrus R&D investments. For every 1.00 Realinvested in citrus research, there is an increase of 13.00 Reaisin the values of orange production in São Paulo state.

  • Advances in the measurement of the C-13(d ,p)C-14 cross section using AMS

    Murillo-Morales, S.   Barron-Palos, L.   Chavez, E.   Lopez-Saavedra, E.   Marin-Lambarri, D. J.   Acosta, L.   Murillo, G.   Policroniades, R.   Huerta, A.   Solis, C.   Varela, A.  

    An experimental protocol to study the total cross section for the C-13(d, p)C-14 nuclear reaction via AMS is being currently developed for deuteron energies between 1 and 4 MeV. We started a series of experiments in which two aluminium cathodes filled with natural-graphite (98.9% 12C, 1.1% 13C) samples were irradiated with a deuterium beam of 4 MeV in a 150 degrees RBS configuration at Instituto Nacional de Investigaciones Nucleares 6.0 Tandem Van de Graaff Accelerator (ININ, Mexico). The relative concentrations of C-14/ C-12 were subsequently analyzed using AMS at Laboratorio Nacional de Espectrometria de Masas con Aceleradores (LEMA, UNAM).

  • NUCLEAR STRUCTURE OF Mo-97 FROM THE (d, p) REACTION

    Chowdhury, M. S.   Booth, W.  

    The reaction Mo-96(d,p)Mo-97 has been studied at 12 MeV using the tandem Van de Craaff accelerator and a multi-channel magnetic spectrograph at the Atomic Weapon Research Establishment, Aldermaston, England. Angular distributions of protons are measured at 12 different angles from 5 degrees to 87.5 degrees at an interval of 7.5 degrees and the reaction products are detected in nuclear emulsion plates. Thirty levels in the energy range from 0.000 to 2.458 MeV have been observed and absolute differential cross-sections for these levels have been measured. The data are analyzed in terms of the distorted-wave Born approximation (DM/BA) theory of the direct reactions, and spins, parities and spectroscopic factors are deduced for various levels. Ambiguity in the spin assignments of d(5/)2 and d(3/2) which is allowed in l(n) =3D 2(d, p) transition is removed by using the corresponding L-value of the Mo-95(t,p)Mo-97 reaction at E-t =3D 12 MeV. Determined value of the sum of spectroscopic factors for transfers of d(5/2) neutrons suggests configuration mixing in the ground state of Mo-96 The properties of the levels in Mo-97 are compared with previous experimental results and theoretical predictions.

  • Local structure and p–d hybridization of Mn-doped In2O3 films

    Yukai An   Deqiang Feng   Lingshen Duan   Zhonghua Wu   Jiwen Liu  

    Mn-doped In2O3 films were deposited on Si (1?0?0) substrates by the RF-magnetron sputtering technique. The influence of Mn-doping concentration on the local structure and degree of p–d hybridization was investigated by x-ray absorption spectroscopy at the Mn K-edge and L2,3-edge. The results show that Mn ions dissolve in In2O3 and substitute for In3+ sites in the +2 valence states. With the increase in Mn-doping concentration, the Mn–O bonding distance increases monotonically, but integrated intensities of L2,3 edges increase first and then decrease. It can be concluded that there exists an optimal Mn–O bonding distance for the transition probabilities from the 2p state to the p–d hybridization state, which results in increasing degree of p–d hybridization. So the Mn-doping concentration has a significant effect on the local structure and degree of p–d hybridization in Mn-doped In2O3 films.

  • Higher secant varieties of P(n) x P(m) embedded in bi-degree (1, d)

    Bernardi, Alessandra   Carlini, Enrico   Catalisano, Maria Virginia  

    Let X((1,d))((n,m)) denote the Segre-Veronese embedding of P(n) x P(m) via the sections of the sheaf O(1, d). We study the dimensions of higher secant varieties of X((1,d))((n,m)) and we prove that there is no defective sth secant variety, except possibly for n values of s. Moreover, when ((m+d)(d)) is a multiple of (m + n + 1), the sth secant variety of X((1,d))((n,m)) has the expected dimension for every s. (C) 2011 Elsevier B.V. All rights reserved.
