Phys. Rev. C 47, 1462–1465 (1993)Half-life of 32SiReceived 7 December 1992; published in the issue dated April 1993 Previous measurements of the half-life of 32Si, which is produced by cosmic-ray spallation of 40Ar and of interest for geophysical dating, display large discrepancies. We present a new method for half-life measurements of this and other isotopes. Two samples containing 6.7×108 and 7.4×108 32Si nuclei, respectively, were prepared by implantation of separated projectile fragments. The half-life of 32Si was calculated from the two independent measurements of the specific activity to be 132±13 yr. © 1993 The American Physical Society URL:
