New measurements of ⁷¹Ge decay: Impact on the gallium anomaly

RADIOACTIVITY ⁷¹Ge(EC)[from ⁷⁰Ge(n, X), E=thermal]; measured Eγ, Iγ, X-rays; deduced T_1/2, relative EC rates from different atomic shells P_L/P_K. Constrain explanation for the so-called "gallium anomaly" based on the⁷¹Ge decay. Small (1 cm³) n-type germanium diode activated with thermal neutron from moderated ²⁵²Cf source and used as a detector of ⁷¹Ge decay.
