Abstract

By adding the 0g orbit to the 1s-0d orbitals, a pseudo sdg shell is created. It is demonstrated that the leading pseudo SU(3) states gives a good description of the A = 18 system; calculations in the 20Ne show an enhanced B (E2: 10 → 8).

    A big leap was made by including all the normal parity orbitals in a major shell (See Fig. 1) into one representation of an SU(3) group, called pseudo-SU(3) [4,5]. A shell model truncation based on pseudo-SU(3) has been used extensively with increasing sophistication and success in explaining the spectroscopy of heavy nuclei [54,57–64]. However, the status of pseudospin symmetry provoked the statement “It should be emphasized that at the present time there is no deeper understanding of the origin of these (approximate) degeneracies.
