Construction of Paired States in Axially Symmetric Nuclei and Diabolic Pair Transfer

In axially symmetric nuclei, three forms of paired states can be constructed, i.e., monopole pair, signature pair and ±Ω pair, which are the eigenstates of (J², J_z), (J²_z, R_x(π)), and J_z, respectively. In the cranked shell model, though the energy spectra at ω = 0 are the same for three types of pair interactions, the spectra and spin alignments for ω≠0 are different to a certain extent. It is found that the ω variation of the pair transfer amplitude, particularly the diabolic pair transfer, is quite different for different pair interactions.
