Energy differences in mirror nuclei with Nucleonic Promiscuity Factor

This study examines the mirror energy differences $(\text{MED}_{N_{p}N_{n}})$ in valence mirror nuclei isotopes: Zr, Mo, Ru, Pd, Cd, Te, Xe, Ba, Ce and Nd; W, Os, Pt, Hg, Po, Rn, Ra and Th with the same $N_{p}N_{n}$ values. The $\text{MED}_{N_{p}N_{n}}$ increases with spin and decreases with the Nucleonic Promiscuity Factor, P. The $\text{MED}_{N_{p}N_{n}}$ is comparatively smaller in (h-p)-(p-h) systems than in the (h-p)-(p-p) system.
