THE (p, t) REACTION TO 48Ti AND 49V IN THE (f7/2)n MODEL

Despite the gains in recent years in performing large multiconfiguratlon shell model calculations, the structure of nuclei in the fp shell still presents great computational difficulties. A rather simple and straightforward approach is to consider the extremely restricted ( l f7 /2)n basis for describing properties of nuclei in thxs region, since the lf7/2 shell IS comparatively well isolated from its nelghbouring shells. Such calculations were first done by Ginocchlo and French [1 ] and McCullen, Bayman and Zamick (MBZ) [2]. More recently, a comprehensive calculation has been done by Kutschera, Brown and Ogawa (KBO) [3]. The (1 f7/2) n model has been applied in a consistent manner to all the nuclei in the lf7/2 shell and energy levels, wave functions, transition probabihties and spectroscopic factors for particle transfer reactions have been calculated. In a systematic study of ground-state (p, t) transitions m Ca isotopes [4], we have shown already that the (f7/2) n model works very well in the middle of the shell and needs rather small admixtures from neighbouring orbitals at the extremes of the shell. The nuclei 48Ti and 49V are located near the middle of the lf7/2 shell, and one does fred a good descrIptxon of both the energy levels and electromagnetic
