The precise knowledge of the half-life of the reaction product is of crucial importance for a nuclear reaction cross section measurement carried out with the activation technique. The cross section of the 
(
,n) reaction was measured recently using this experimental approach. The preliminary results indicated that the literature half-life of , derived about half a century ago, is overestimated. Therefore, the half-lives of and its daughter isotope and have been measured with high precision using -spectroscopy. The results are 
h for , 
h for and 
d for . The precision of the half-life values has been increased, consequently the recently measured (,n) activation cross section will become more precise.
