Neutron transfer in ^9 Be + ^159 Tb system
The European Physical Journal A(2021)
摘要
One neutron stripping cross sections ( σ _-1n ) are measured in ^9 Be+ ^159 Tb system in the energy range E _cm /V _B ∼ 0.79–1.24 using offline gamma counting technique. The CRC model calculations including the ground state and the 2 ^+ resonance state of ^8 Be, carried out using the FRESCO code, give a reasonable description of the measured data. In addition, comparisons of reduced 1n-stripping cross sections- σ _red with ^9 Be for different target nuclei (A ∼ 150–200), and σ _red for ^9 Be, ^6 Li with ^159 Tb target are presented. While no strong target dependence is observed with ^9 Be projectile, σ _red ( ^9 Be) is significantly larger than that for ^6 Li, which is consistent with the Q-value for transfer reactions and breakup threshold energy of projectiles.
