Time-dependent mean-field determination of the excitation energy in transfer reactions: Application to the reaction 238U on 12C at 6.14 MeV/nucleon

Abstract :
The internal excitation of nuclei after multinucleon transfer is
estimated by using the time-dependent mean-field theory. Transfer
probabilities for each channel as well as the energy loss after
reseparation are calculated. By combining these two pieces of
information, we show that the excitation energy distribution of
the transfer fragments can be obtained separately for the
different transfer channels. The method is applied to the reaction
involving a 238U beam on a 12C target, which has recently been
measured at GANIL. It is shown that the excitation energy
calculated with the microscopic theory compares well with the
experimental observation, provided that the competition with
fusion is properly taken into account. The reliability of the
excitation energy is further confirmed by the comparison with the
phenomenological heavy-ion phase-space model at higher
center-of-mass energies.
