Nuclear-structure calculations with the modified Yale potential for the 2s-1d shell

Employing the unitary-model approach of Shakin, Waghmare, Tomaselli, and Hull, and a modified version of the Yale potential, adjusted to yield a lower percentage of the "D" state in the deuteron ground state without affecting the other two-nucleon quantities calculable from the Yale potential, the ground-state properties of the even-even N=Z nuclei are calculated for the 2s-1d shell by using the Hartree-Fock self-consistent approach. The healing distance for the relative ³S₁ state is not used as a parameter since healing is "naturally" achieved for this state. Using the same values of the oscillator and level-shift parameters, the modified Yale interaction with its reduced tensor force component yields binding energies, single-particle energies, rms radii, and deformations which are generally closer to the experimental values than those reported for the Yale potential.[NUCLEAR STRUCTURE ¹⁶O, ²⁰Ne, ²⁴Mg, ²⁸Si, ³²S, ³⁶A, ⁴⁰Ca; calculated single-particle energies, ground-state energies, rms radii, and ground-state deformations.
