Abstract Precise measurements have been made of the half-life of P32 produced by both the S32 (n, p) P32 and P31 (n, γ)P32 reactions. Consideration has been given to systematic errors including possible radiochemical impurities and a value of 14.290 days is obtained for the half-life of P32 with a statistical error of ±0.014 days evaluated at one ...

Direct observation of the 218Po alpha-peak decay with a microcomputer-controlled alpha-spectrometer yielded a mean half-life value of 3.040 +/- 0.008 min, where the error quoted represents twice the standard deviation of the means from 38 separate decay measurements.

This work measured the half life of radioisotope (175)Hf, which was produced by neutron activation method at the ZF-300-II Intense Neutron Generator in Lanzhou University. The half life of (175)Hf, measured by γ-ray spectrometry using a well calibrated GEM-60P coaxial High Purity Germanium (HPGe) detector, has been found to be 70.65±0.19 days.

Half life of 135Sb and evidence on the half life of 134Sb
Journal of Inorganic and Nuclear Chemistry, 1964Abstract A search for delayed-neutron precursors among the short-lived antimony fission products was unsuccessful. This result suggested that either (1) the neutron branching of the possible precursors 134 Sb and 135 Sb is extremely small or (2) that the half lives of those isotopes are much shorter than the upper limits previously reported (45 and
