26 Dec 2001 | | Journal: | Phys.Rev. C66 (2002) 034302 | | Subject: | nucl-th | | Abstract: | We propose a simple approach to predict the angular momentum I ground state (I g.s.) probabilities of many-body systems that does not require the diagonalization of hamiltonians with random interactions. This method is found to be applicable to {f all} cases that have been discussed: even and odd fermion systems (both in single-j and many-j shells), and boson (both sd and sdg) systems. A simple relation for the highest angular momentum g.s. probability is found. Furthermore, it is suggested for the first time that the 0g.s. dominance in boson systems and in even-fermion systems is given by two-body interactions with specific features. | | Source: | arXiv, nucl-th/0112075 | | Services: | Forum | Review | PDF | Favorites | |
