Precise half-life measurement of 110Sn and 109In isotopes

The half-lives of ¹¹⁰Sn and ¹⁰⁹In isotopes have been measured with high precision. The results are T_1/2=4.173±0.023 h for ¹¹⁰Sn and T_1/2=4.167±0.018 h for ¹⁰⁹In. The precision of the half-lives has been increased by a factor of 5 with respect to the literature values, thereby making results of the recently measured ¹⁰⁶Cd(α,γ)¹¹⁰Sn and ¹⁰⁶Cd(α,p)¹⁰⁹In cross sections more reliable.
