Spin-trap isomers in deformed, odd-odd nuclei in the light rare-earth region near N=98

ATOMIC MASSES ^{156,156m,158,160,160m}Pm, ^{158,160,160m,162,162m,164}Eu, ^{162,162m,164,164m,166}Tb; measured cyclotron frequency using the Canadian Penning Trap mass spectrometer at the CARIBU-ANL facility; deduced mass excesses, isomer excitation energies, Kπ, Nilsson configurations. Radioactive nuclei were produced in spontaneous fission of ²⁵²Cf source, filtered by A/Q, and purified by a multireflection time-of-flight mass separator (MR-TOF). Comparison with multiquasiparticle blocking calculations.
