CONSTRUCTION OF PAIRED STATES IN AXIALLY-SYMMETRICAL NUCLEI AND DIABOLIC PAIR TRANSFER

In axially symmetric nuclei, three forms of paired states can be const ructed, i.e., monopole pair, signature pair and +/-Omega pair, which a re the eigenstates of (J(2), J(z)), (J(z)(2), R-x(pi)), and J(z), resp ectively. In the cranked shell model, though the energy spectra at ome ga = 0 are the same for three types of pair interactions, the spectra and spin alignments for omega not equal 0 are different to a certain e xtent. it is found that the omega variation of the pair transfer ampli tude, particularly the diabolic pair transfer, is quite different for different pair interactions.
