Messung des Elektroneneinfang am Kern Ga70

The electron capture of Ga⁷⁰ has been observed using a x-ray semiconductor Ge(Li) detector. Measuring the ZnK x-rays and the 0.1755 MeV gamma-rays from the beta decay of Ga⁷⁰ the transition probability to the ground state ofZn⁷⁰ was found to be 0.24%. The log(ft) value is 4.8. The half-life of Ga⁷⁰ has been found to be (21.15±0.06) min and the energies of the gamma-rays are (0.1755±0.0005) MeV and (1.040±0.003) MeV.
