Nuclear matter properties with the re-evaluated coefficients of liquid drop model

摘要

The coefficients of the volume, surface, coulomb, asymmetry and pairingenergy terms of the semiempirical liquid drop model mass formula have beendetermined by furnishing best fit to the observed mass excesses. Slightlydifferent sets of the weighting parameters for liquid drop model mass formulahave been obtained from minimizations of chisquare and mean square deviation.The most recent experimental and estimated mass excesses fromAudi-Wapstra-Thibault atomic mass table have been used for the least squarefitting procedure. Equation of state, nuclear incompressibility, nuclear meanfree path and the most stable nuclei for corresponding atomic numbers, all arein good agreement with the experimental results.
