摘要

Abstract

This study utilizes large-scale shell model calculations with the extended pairing and multipole-multipole force model (EPQQM) to investigate low-lying states in the nuclei of ,42,Ca,42,Sc, and ,42-44,Ti. The model space in this study includes the ,fp, shell as well as the intruder ,g,9/2, orbit, which accurately reproduces the positive parity levels observed in the aforementioned nuclei and predicts high-energy states with negative parity coupled with the intruder ,g,9/2,. The study further predicts two different configurations in ,43,Ti at around 6 MeV, specifically , $π f_{7 / 2}^{2} ν g_{9 / 2}$ , and ,πf,7/2,g,9/2,vf,7/2, both of which involve the intruder orbit ,g,9/2,. The levels coupled with the intruder ,g,9/2, in ,44,Ti are predicted to lie between 7 and 11 MeV. The inclusion of the intruder orbit ,g,9/2, is crucial for the exploration of high-energy states in the northeast region of the doubly magic nucleus ,40,Ca.
