Half-life determination of 88Y and 89Sr.
Half-life measurements have been carried out at LNHB for 88Y using a 4pi gamma-ionisation chamber and for 89Sr using a proportional counter. The determined half-life values and associated standard uncertainties are 106.63 +/- 0.05 d for 88Y and 50.65 +/- 0.05 d for 89Sr, being consistent with relevant values reported in literature. Based on the present results and relevant literature values revised recommended half-life values and associated standard uncertainties are proposed, viz. 106.626 +/- 0.021 d for 88Y and 50.57 +/- 0.03 d for 89Sr.
