A new mass formula and new neutron and proton magic numbers in light nuclei

This mass formula explains gross features of the binding energy curves for all the elements from Li to Bi. It has no shell effects incorporated. Comparisons of separation energies computed from this formula and measured masses show extra-stability at N = 6 (Z = 3-8), Z =6 (N = 6-9), N = 14 (Z 7-10), Z = 14 (N = 14-19), N = 16 (Z = 7-8), Z = 16 (N = 24-26), loss of magicity at N = 8 (Z = 4), N = 20 (Z = 12-15) and quenching of N =50, 82, 126, Z = 50 near driplines. Z = 82 magicity rises at N = 104 after strong quenching near N = 107. (author)
