Anomalies in the alpha-decay energies and half-lives of neutron-deficient Po isotopes
2001 (English)In: Hyperfine Interactions, ISSN 0304-3843, E-ISSN 1572-9540, Vol. 132, no 04-jan, 141-146 p.Article in journal (Refereed) Published
The transition rates of DeltaL = 0 alpha transitions in them lightest Po isotopes are considerably slower than the transition rates of the heavier ones, even leading to a considerable deviation in the classical Geiger-Nuttall plot. Evidence will be given that due to particle-hole excitations through the Z = 82 proton shell, the groundstate of the lighter Po isotopes becomes deformed and direct alpha decay to the spherical groundstate of the corresponding Ph isotopes is highly retarded.
