Abstract

The beta ⁺/EC decay of mass-separated ¹⁰⁴Sn and ¹⁰⁵Sn isotopes was studied by X-ray and gamma -ray singles, as well as by X- gamma and gamma - gamma coincidences. Sources were produced in the reactions ⁹²Mo (²⁰Ne,ypxn). The nucleus ₅₀¹⁰⁴Sn with T₁2/=23+or-2 s was identified. A partial decay scheme of ¹⁰⁵Sn is proposed.
