Multinucleon transfer with time-dependent covariant density functional theory

The microscopic framework of time-dependent covariant density functional theory is applied to study multinucleon transfer reactions with transfer probabilities calculated using the particle number projection method. It is found that similar total cross sections are obtained with two different relativistic density functionals, PC-PK1 and DD-ME2, as well as with the Skyrme functional SLy5 in a previous study, for multinucleon transfer in the reactions: ⁴⁰Ca+¹²⁴Sn at Elab=1700.16em0exMeV, ⁴⁰Ca+²⁰⁸Pb at Elab=2490.16em0exMeV, and ⁵⁸Ni+²⁰⁸Pb at Elab=328.40.16em0exMeV. We report the microscopic calculation of total cross sections for the reactions: ⁴⁰Ar+²⁰⁸Pb at Elab=2560.16em0exMeV and ²⁰⁶Pb+¹¹⁸Sn at Elab=12000.16em0exMeV. Compared to the results obtained with the GRAZING model, the cross sections predicted by the time-dependent covariant density functional theory are in much better agreement with data, and demonstrate the potential of microscopic models based on relativistic density functionals for the description of reaction dynamics.
