Description
Exploring the nuclear shell structure of neutron-rich $N=50$ nuclei is one of the most interesting and mysterious phenomena in nuclear physics, and it has become the forefront of both experimental and theoretical research in recent years. We have constructed the shell model Hamiltonian in the $\pi(fp)$-$\nu(sdg)$ model space based on {\it ab-initio} approach VS-IMSRG($3{\rm f}_2$) with minimal phenomenological adjustments to the single-particle energies to reproduce the recently available experimental data in $N = 50$ region. To perform the large-scale shell model calculations, we have carried out the state-of-the-art advanced Monte-Carlo Shell Model (MCSM) to interpret the nuclear structure properties of nuclei near the neutron magic number $N = 50$. Our MCSM calculated nuclear structure properties with the new shell model Hamiltonian based on VS-IMSRG($3{\rm f}_2$) is obtained in a rather good qualitative agreement with the experimental data and previous shell model predictions. The prediction of structural properties in the $N=50$ region has important implications for nuclear astrophysics, as they influence nucleosynthesis pathways and contribute to the distribution of elemental abundance in the universe.
