A Hamiltonian matrix diagonalization (HMD) method is applied to calculate the lowest several bands in [sup 230,232,234]Th. Neutron pair transfer strength distributions are calculated and compared between HMD and cranked Hartree-Fock-Bogoliubov plus Random Phase Approximation (CHFB+RPA). Sudden-approximation methods are applied to estimate pair transfer population patterns in [sup 206]Pb + [sup 232]Th reactions. Band-crossing, pairing, and spin alignment properties are also discussed.
