Coefficients of the isobaric mass equation and their correlations with various nuclear parameters

The coefficients of the isobaric multiplet mass equation M = a + bT(z) + cT(z)(2) have been calculated for the 430 identified T = 1/2, 1, 3/2, 2 multiplets and correlations of its b, c coefficients with various nuclear parameters have been sought. For most mass numbers A there is a tendency for b to increase, and for c to decrease, with the average excitation energy of the multiplet. There seems to be no separate dependence of b or c on spin, but there could be a dependence of b on parity. (C) 1998 Academic Press.
