Abstract
The decay scheme of has been studied in detail to obtain information on the -decay mirror symmetry properties of the mass-20 multiplet and to determine the Fermi decay strength to the isobaric analog state in . The ratio was determined to be 1.026 ± 0.024 for the transitions to the first excited state of . The value for the transition to the -MeV level was measured to be 2992 ± 233 sec indicating that most of the Fermi strength is concentrated in this transition. A weak transition from the isobaric analog state to the first excited state of was observed and new -delayed groups are reported at 3.27, 5.272, and 5.701 MeV. Theoretical values derived from the shell-model wave functions are compared with experiment.
