Half-Life ofSi32from Tandem-Accelerator Mass Spectrometry

Abstract

In one of the first applications of the new accelerator mass-spectrometry technique to nuclear physics problems, the half-life of ${}_{}{}^{32}{}_{}{}^{}\mathrm{Si}$ has been determined to be 108±18 yr. This result, which disagrees with the accepted value of 330±40 yr, has special significance because of the use of ${}_{}{}^{32}{}_{}{}^{}\mathrm{Si}$ for dating studies.
