Neutron transfer in ${}^9$Be + ${}^{159}$Tb system

Abstract

One neutron stripping cross sections (${\sigma }_{-1n}$) are measured in ${}^9$Be+${}^{159}$Tb system in the energy range E${}_{cm}$/V${}_B$ $\sim$ 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- ${\sigma }_{red}$ with ${}^9$Be for different target nuclei (A $\sim$150-200), and ${\sigma }_{red}$ for ${}^9$Be, ${}^6$Li with ${}^{159}$Tb target are presented. While no strong target dependence is observed with ${}^9$Be projectile, ${\sigma }_{red}$(${}^9$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.
