在新的加速器质谱技术首次应用于核物理问题中,$^{32}\mathrm{Si}$的半衰期被确定为108\ifmmode\pm\else\textpm\fi{}18年。这一结果与公认的330\ifmmode\pm\else\textpm\fi{}40 yr值不一致,但由于使用了$^{32}\mathrm{Si}$进行测年研究,因此具有特殊意义。
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\ifmmode\pm\else\textpm\fi{}18 yr. This result, which disagrees with the accepted value of 330\ifmmode\pm\else\textpm\fi{}40 yr, has special significance because of the use of $^{32}\mathrm{Si}$ for dating studies.
