The half-life of /sup 32/Si has been measured to be T/sub 1/2/=101 +- 18 yr, considerably shorter than the previously accepted value of approx. =300 yr. The new value was obtained by measuring the specific ..beta.. activity with a liquid--scintillation-counter technique and the /sup 32/Si concentration with tandem-accelerator mass spectrometry. It is expected that the present result will have a strong impact on studies with cosmogenic /sup 32/Si.
