Lifetime of the 3.830-MeV state of Ca41

The mean lifetime of the 3.830-MeV state of $^{41}\mathrm{Ca}$ was determined from the delayed coincidence measurements between neutrons and $\ensuremath{\gamma}$ rays from the $^{28}\mathrm{Si}(^{16}\mathrm{O}, 2pn\ensuremath{\gamma})^{41}\mathrm{Ca}$ reaction at 40-MeV incident energy using the direct timing method. The value of 4.16\ifmmode\pm\else\textpm\fi{}0.20 nsec obtained is smaller but consistent with the "plunger" values previously reported.NUCLEAR REACTIONS $^{28}\mathrm{Si}(^{26}\mathrm{O}, 2pn\ensuremath{\gamma})$, $E=40$ MeV.
