Abstract
An atomic mass formula is constructed as the sum of a gross part and empirical shell terms. The gross part is adjusted so that the shell terms may remain small and accord with the charge symmetry of nuclear forces. The shell terms show marked dips at the magic numbers 28, 50, 82 and 126, but not at 8 and 20. The standard deviation is 300 keV for even-even odd-mass nuclei with mass number 1 to 257. For odd-odd nuclei the mass formula includes additional terms and the standard deviation is 435 keV.Keywords
