Abstract

The magnetic moments of the first 3/2⁺ states of ^{203, 205, 207}Tl are discussed in terms of mesonic-exchange and configuration-mixing corrections. The gyromagnetic ratios of two fission isomeric states of ²³⁷Pu are discussed in terms of Nilsson states for the second well in the potential energy surface. The gyromagnetic ratios of high spin states of ¹⁶⁴Er and ¹⁶⁰Dy are discussed in terms of Coriolis-Anti-Pairing and Rotation-Alignment theories. A new type of seniority quantum number, related to the number of nucleons in time-reversal-conjugate states, is proposed as an explanation for the occurrence of rotational-type quadrupole moments in deformed as well as spherical nuclei. Further tests of this seniority classification are suggested on the basis of the quadrupole moments of high-spin states and first 3⁺ states.
