3 Sep 2003 | | Journal: | Phys.Rev. C68 (2003) 061301 | | Subject: | nucl-th nucl-ex | | Abstract: | Excited 0+ states are studied in the framework of the projected shell model, aiming at understanding the nature of these states in deformed nuclei in general, and the recently observed 13 excited 0+ states in 158Gd in particular. The model, which contains projected two- and four-quasiparticle states as building blocks in the basis, is able to reproduce reasonably well the energies for all the observed 0+ states. The obtained B(E2) values however tend to suggest that these 0+ states might have a mixed nature of quasiparticle excitations coupled to collective vibrations. | | Source: | arXiv, nucl-th/0309007 | | Services: | Forum | Review | PDF | Favorites | |
