Abstract

A coexisting band structure is identified in ¹⁵²Sm through γ-ray coincidence spectroscopy following β decay of ^152m,gEu and following multistep Coulomb excitation. This structure is interpreted as a pairing isomer analogous to a similar band identified in ¹⁵⁴Gd, based on relative B(E2) values for transitions out of the band and two-neutron transfer reaction population of the 0⁺ and 2 ⁺ band members. Systematics for odd-A isotopes near N = 90 suggest that there should be a low-lying pairing isomer in ¹⁵⁶Dy and similar structures at higher energy in ¹⁵⁰Nd and ¹⁵⁸Er.
