摘要: Abstract Hamiltonians for shell-model calculations of isospin-nonconserving (INC) processes are determined empirically by requiring that they reproduce experimentally measured isotopic mass shifts. Five separate configuration spaces were considered: the 0p; 0 p 1 2 , d 5 and s ; Is-0d; 3 f 7 0f-1p spaces. The INC hamiltonian was assumed to be comprised Coulomb force plus phenomenological nucleon-nucleon interactions. parameters isovector single-particle energies, overall strength, isotensor strengths interaction; obtained performing a least-squares fit experimental b- c-coefficients isobaric-mass-multiplet equation.
