Title: Structure of ${}^{107}{Sn}$ studied through single-neutron knockout reactions

Abstract

The neutron-deficient nucleus Sn-107 has been studied by using the one-neutron knockout reaction. By measuring the decay gamma rays and momentum distributions of reaction residues, the spins of the ground, 5/2⁺, and first-excited, 7/2⁺, states of Sn-107 have been assigned by comparisons to eikonal-model reaction calculations. We also observed limits on the inclusive and exclusive cross sections and transitions due to neutron removals from below the N = 50 closed shell have been observed. New excited states up to 5.5 MeV in Sn-107 have been identified.

Structure of ${}^{13}{Be}$ studied in proton knockout from ${}^{14}B$

Journal Article Ribeiro, G. ; Nácher, E. ; Tengblad, O. ; ... - Physical Review C

The neutron-unbound isotope ¹³Be has been studied in several experiments using different reactions, different projectile energies, and different experimental setups. There is, however, no real consensus in the interpretation of the data, in particular concerning the structure of the low-lying excited states. Gathering new experimental information, which may reveal the ¹³Be structure, is a challenge, particularly in light of its bridging role between ¹²Be, where the N = 8 neutron shell breaks down, and the Borromean halo nucleus ¹⁴Be . The purpose of the present study is to investigate the role of bound excited states in the reaction product ¹²Bemore »« less

Journal Article Liang, J. Felix ; Allmond, J. M. ; Gross, C. J. ; ... - Physical Review C

In this study, the presence of neutron transfer channels with positive Q values can enhance sub-barrier fusion cross sections. Recent measurements of the fusion excitation functions for ⁵⁸Ni+^132,124Sn found that the fusion enhancement due to the influence of neutron transfer is smaller than that in ⁴⁰Ca +^132,124Sn although the Q values for multineutron transfer are comparable. The purpose of this study is to investigate the differences observed between the fusion of Sn + Ni and Sn + Ca. Methods: Fusion excitation functions for ^46,50Ti +¹²⁴Sn have been measured at energies near the Coulomb barrier. As a result, a comparison ofmore »« less

Elastic, inelastic, and $1 n$ transfer cross sections for the ${}^{10}B + {}^{120}{Sn}$ reaction

Journal Article Gasques, L. R. ; Freitas, A. S. ; Chamon, L. C. ; ... - Physical Review C

The ¹⁰B+¹²⁰Sn reaction has been investigated at E_Lab=37.5 MeV. The cross sections for different channels, such as the elastic scattering, the excitation of the 2⁺ and 3^-120Sn states, the excitation of the 1⁺ state of ¹⁰B, and the 1n pick-up transfer, have been measured. One-step distorted-wave Born approximation and coupled-reaction-channels calculations have been performed in the context of the double-folding São Paulo potential. Here, the effect of coupling the inelastic and transfer states on the angular distributions is discussed in the paper. In general, the theoretical calculations within the coupled-reaction-channels formalism yield a satisfactory agreement with the corresponding experimental angularmore » distributions.« less
