Time-dependent Hartree-Fock calculations for multi-nucleon transfer processes: Effects of particle evaporation on production cross sections

摘要

We present a microscopic calculation of multi-nucleon transfer reactionsemploying the time-dependent Hartree-Fock (TDHF) theory. In our previouspublication [Phys. Rev. C 88, 014614 (2013)], we reported our analysis for themulti-nucleon transfer processes for several systems. Here we discuss effectsof particle evaporation processes on the production cross sections. Sinceparticle evaporation processes may not be described adequately by the TDHFcalculations, we evaluate them using a statistical model. As an input of thestatistical model, excitation energies of the final fragments are necessary. Weevaluate them from the TDHF wave function after collisions, extending theparticle number projection technique. From the calculation, the particleevaporation effects are found to improve descriptions of the production crosssections. However, the production cross sections are still underestimated forprocesses where a number of protons are transferred. Possible origins of thediscrepancy are discussed.
