Abstract

The multi-nucleon transfer reactions 30Si(18O,17F)31Al and 30Si(13C, 14O)29Mg have been investigated at incident energies of 100 and 93 MeV respectively and a mean reaction angle of 8°. Excited states of the Tz = 5 2 nuclei 31Al and 29Mg have been studied and a mass excess of -14.967 ± 0.025 MeV obtained for the ground state of 31Al. The 28Si(18O,17F)29Al and 28Si(13C, 14O)27Mg reactions have also been studied, enabling conclusions to be drawn concerning the probable structure of many of the states observed in 31Al and 29Mg. Several 0h{stroke}ω levels predicted in recent complete sd-shell calculations have been assigned experimental counterparts for the first time. The results also support a previous suggestion that negative-parity states occur in 29Mg at 1.10 and 1.46 MeV.
