Improvement in a phenomenological formula for ground state binding energies
Abstract
The phenomenological formula for ground state binding energy derived earlier (International Journal of Modern Physics E 20 (2011) 179) has been modified. The parameters have been obtained by fitting the latest available tabulation of experimental values. The major modifications include a new term for pairing and introduction of a new neutron magic number at N=160. The new formula reduced the root mean square deviation to 363 keV, a substantial improvement over the previous version of the formula.
