First search for $\alpha$ decays of naturally occurring Hf nuclides with emission of $\gamma$ quanta

F. A. Danevich, M. Hult, D. V. Kasperovych +7

The first ever search for $\alpha$ decays to the first excited state in Yb was performed for six isotopes of hafnium (174, 176, 177, 178, 179, 180) using a high purity Hf-sample of natu…
