Ground State Properties 


The force used in the HartreeFockBogoliubov (HFB) mass model is an extended Skyrme force (containing t_{4} and t_{5} terms), along with a 4parameter deltafunction pairing force derived from realistic calculations of infinite nuclear and neutron matter.
The total binding energy is given by E_{tot }= E_{HFB}+ E_{wigner} where
The parameter set, labelled BSk24, is determined by constraining the nuclearmatter symmetry coefficient to J = 30 MeV and the isoscalar effective mass to M*_{s}/M = 0.8 and optimizing the fit to the full data set of the 2353 measured masses with N,Z ≥ 8 (both spherical and deformed) of Audi et al. [Chinese Physics C36, 1287 (2012)]: the corresponding root mean square error is 0.549 MeV for this data set.
