Role of neutron transfer in the reaction mechanism of ${}^9$Be+${}^{169}$Tm, ${}^{181}$Ta, ${}^{187}$Re and ${}^{197}$Au systems

Abstract

The contribution of one neutron stripping cross section to the total reaction cross section has been studied for ${}^9$Be projectile incident on ${}^{169}$Tm, ${}^{181}$Ta, ${}^{187}$Re and ${}^{197}$Au targets around Coulomb barrier energy. The measured one neutron stripping cross sections for these systems have been compared with the coupled channel calculations. The recently developed global set of optical model potential parameters for ${}^9$Be projectile has been used in the present calculations. The cumulative of measured complete fusion (CF), incomplete fusion (ICF), one neutron stripping and calculated non-capture breakup (NCBU) cross sections is found to explain almost the reaction cross sections for all the targets. A very small contribution from target inelastic states and elastic breakup may contribute to the remaining part. The percentage fraction of cross section for CF, ICF, one neutron stripping, and NCBU over reaction cross section show the dominance of neutron transfer and NCBU at below barrier energies while CF and ICF processes have the major contribution at above barrier energies.
