摘要: Energies and spectroscopic factors of the first 7/2-, 3/2-, 1/2-, 5/2- states in (35)Si21 nucleus were determined by means (d, p) transfer reaction inverse kinematics at GANIL using MUST2 EXOGAM detectors. By comparing information on Si35 S37 isotones, a reduction p3/2-p1/2 spin-orbit splitting about 25% is proposed, while f7/2-f5/2 seems to remain constant. These features, derived after having unfolded nuclear correlations shell model calculations, have been attributed properties two-body interaction, amplitude which for time an atomic nucleus. The present results, remarkably well reproduced several realistic nucleon-nucleon forces, provide unique touchstone modeling interaction nuclei.
