Angular correlation and lifetime measurements in $sup 22$Ne

摘要: Particle-$gamma$ angular correlations have been measured for a number of states above 7.3 MeV in $sup 22$Ne using the 18$O($sup 7$Li, t$gamma$)$sup reaction with tritons observed at 0degree. New information on spins and parities several was obtained. In addition, by demonstrating that nuclei were strongly aligned, these measurements provide support direct $alpha$-particle transfer mechanism t)$sup reaction. Angular correlation lifetime employing 19$F($alpha$, p$gamma$)$sup also performed 22$Ne, including closely spaced doublets which previous is incomplete or inconsistent. Lifetimes Doppler-shift attenuation method. The results are compared recent large basis shell model calculations. (AIP)
