报告摘要

As the indicator ofthe number of the particles that are not paired to zero spin, the concept of seniority was applied implicitly to account for the crucial pairing channel inthe residual nuclear Hamiltonian. Since then, the seniority scheme has been known to be extremely useful in semimagic and neighboring nuclei dominated by the correlation of identical fermions in a single-j orbit. The seniority symmetry is realised to be partially conserved in two special cases of the (9/2)⁴ system, which can lead to striking features in the corresponding spectroscopy and related electromagnetic transition properties. However, it is still quite difficult to examine and derive these solvable states given a single-j Hamiltonian, especially towards higher j orbits. To this end, we develop a novel and effective way to confront this challenge, which allows us to explore another special family of seniority conserved states in the mid-shell besides the limited case of (9/2)⁴ configuration. Moreover, we study all the states in single-j systems up to j = 15/2 and give the analytic expressions for the eigenvalues of all solvable states with a focus on those in j = 9/2 and j =11/2.
