英文摘要 | In a calculation of rotated matrix elements with angular momentum projection, the generalized Wick's theorem may encounter a practical problem of combinatorial complexity when the configurations have more than four quasiparticles (qp's). The problem can be solved by employing the Pfaffian algorithm generally applicable to calculations of matrix elements for Hartree-Fock-Bogoliubov states with any number of qp's. This breakthrough in many-body techniques enables studies of high-spin states in a shell-model framework. As the first application of the Pfaffian algorithm, the configuration space of the projected shell model is expanded to include 6-qp states for both positive and negative parities. Taking Hf-166 as an example, we show that 6-qp states become the main configuration of the yrast band beyond spin I approximate to 34 (h) over bar, which explains the observed third back-bending in moment of inertia. Structures of multi-qp high-K isomers in Hf-176 are analyzed as another example. |
