Investigating neutron transfer in the ${}^9$Be + ${}^{197}$Au system

Abstract

In this work $\text{n}$-transfer and incomplete fusion cross sections for ${}^9$Be + ${}^{197}$Au system are reported over a wide energy range, E${}_{c.m.}$ $\approx$ 29-45 MeV. The experiment was carried out using activation technique and off-line gamma counting. The transfer process is found to be the dominant mode as compared to all other reaction channels. Detailed coupled reaction channel (CRC) calculations have been performed for $\text{n}$-transfer stripping and pickup cross sections. The measured 1$\text{n}$-stripping cross sections are explained with CRC calculations by including the ground state and the 2${}^{+}$ resonance state (E = 3.03 MeV) of ${}^8$Be. The calculations for 1$\text{n}$-pickup, including only the ground state of ${}^{10}$Be agree reasonably well with the measured cross sections, while it overpredicts the data at subbarrier energies. For a better insight into the role of projectile structure in the transfer process, a comprehensive analysis of 1$\text{n}$-stripping reaction has been carried out for various weakly bound projectiles on ${}^{197}$Au target nucleus. The transfer cross sections scaled with the square of total radius of interacting nuclei show the expected Q-value dependence of 1$\text{n}$-stripping channel for weakly bound stable projectiles.
