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 T_z = 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.
