Many-Body Approximations in the sd-Shell Sandbox
arXiv:0806.3488 · doi:10.1103/PhysRevC.78.044304
Abstract
A new theoretical approach is presented that combines the Hartree-Fock variational scheme with the exact solution of the pairing problem in the finite orbital space. Using this formulation in the sd-space as an example, we show that the exact pairing significantly improves the results for the ground state energy
