New parametrization for the nuclear covariant energy density functional with a point-coupling interaction
New parametrization for the nuclear covariant energy density functional with a point-coupling interaction
A new parametrization PC-PK1 for the nuclear covariant energy density functional with nonlinear point-coupling interaction is proposed by fitting to observables for 60 selected spherical nuclei, including the binding energies, charge radii and empirical pairing gaps. The success of PC-PK1 is illustrated in its description for infinite nuclear matter and …
