Abstract

X-ray spectra of natural germanium sample irradiated in the fast neutron flux were measured using Si(Li)-detector during 4800 hours. The half-life of the \({}^{71}\)Ge nucleus was evaluated to be \(T_{1/2}=11.4645\pm 0.0036\) days that is consistent with the recent results whilst having a higher accuracy. The possibility of explaining the ‘‘gallium anomaly’’ due to a longer lifetime of \({}^{71}\)Ge nucleus is therefore strictly rejected.

一种新的精确测量\({}^{{71}}\) Ge寿命的方法

用Si（Li）探测器测量了天然锗样品在快中子辐照4800小时内的x射线能谱。估算出\({}^{71}\) Ge核的半衰期为\(T_{1/2}=11.4645\pm 0.0036\)天，与最近的结果一致，同时具有更高的准确性。因此，严格拒绝了解释“镓异常”的可能性，因为\({}^{71}\) Ge核的寿命更长。

期刊介绍： Physics of Atomic Nuclei is a journal that covers experimental and theoretical studies of nuclear physics: nuclear structure, spectra, and properties; radiation, fission, and nuclear reactions induced by photons, leptons, hadrons, and nuclei; fundamental interactions and symmetries; hadrons (with light, strange, charm, and bottom quarks); particle collisions at high and superhigh energies; gauge and unified quantum field theories, quark models, supersymmetry and supergravity, astrophysics and cosmology.
