Positions (r(k)) and sigmas (σ(k)) of the Gaussian packets can be found by applying minimization procedure to the Hamiltonian:

12 C 72 Kr r (fm) ρ(nucleons/fm 3 )

Conclusions: ρ 0 = nuc/fm 3 e 0 = MeV K 0 = 350 MeV μ = /fm 2 Z=N Z= , evet-event nuclei New form of EOS permits analiticaly integrate the hamiltonian density given as the sum of the Gaussian packets Proposed surface term properly describes nuclear matter density on the surface With more extensive calculations for, neutron skins and binding energies of nuclei in the ground states, parameters of EOS can be more constrained One can used this new form of EOS in the QMD type calculation
