Mean Lifetimes of Low-Lying Levels ofS34

The mean lifetimes of the levels of ${}_{}{}^{34}{}_{}{}^{}\mathrm{S}$ below 5.0-MeV excitation energy have been measured by the Doppler-shift attentuation method. The ${}_{}{}^{31}{}_{}{}^{}\mathrm{P}(\alpha , p){}_{}{}^{34}{}_{}{}^{}\mathrm{S}$ reaction was used to populate these states. GaP targets evaporated onto 1-μ Ni foils were bombarded with $\alpha$ particles ranging in energy from 5.0 to 7.3 MeV. $\gamma$ rays were detected with a 30-cc Ge(Li) detector at 0, 90, and 143° to the beam axis. The following mean lifetimes were found: $\tau (2.13-\mathrm{MeV}\mathrm{level})=400\mathrm{}\pm 32$ fsec, $\tau \mathrm{}\left(3.30\right)=175\mathrm{}\pm 25$ fsec, $\tau \mathrm{}\left(3.92\right)>1.39\mathrm{}$ psec, $\tau \mathrm{}\left(4.07\right)<24\mathrm{}$ fsec, $\tau \mathrm{}\left(4.11\right)=110\mathrm{}\pm 10$ fsec, $\tau \mathrm{}\left(4.62\right)=135\mathrm{}\pm 17$ fsec, $\tau \mathrm{}\left(4.69\right)=131\mathrm{}\pm 13$ fsec, $\tau \mathrm{}\left(4.88\right)=(57\mathrm{}\pm 22 \mathrm{fsec})$,, $\tau \mathrm{}\left(4.89\right)=(52\mathrm{}\pm 14 \mathrm{fsec})$.
