Abstract
In order to provide data for the simulation of the astrophysical γ-process, the cross section measurement of the 124Xe(p,γ)125Cs reaction is in progress at MTA Atomki using the activation technique. Precise information on the decay characteristics of the reaction products is of crucial importance for measurements carried out using this method. The half-lives of the produced 125Cs and its daughter 125Xe are published in previous works, but with large uncertainties and ambiguous values. To make these nuclear parameters more precise, the half-lives have been re-measured with high precision using γ-spectroscopy. The obtained new half-life values are t1/2 = 44.35 ± 0.29 minutes for 125Cs and t1/2 = 16.87 ± 0.08 hours for 125Xe.
