Interpretation of the fine structure in the C14 radioactive decay of Ra223

Sheline, Raymond K. and Ragnarsson, Ingemar LU (1991) In Physical Review C 43(3). p.1476-1479
Abstract

The experimental hindrance factors determined from the fine structure in the C14 decay of Ra223 are strikingly similar to the hindrance factors observed in the alpha decay of odd-A reflection-asymmetric deformed nuclei in spite of the deformed to spherical shape which occurs in the C14 decay. Calculations of the overlap between the reflection-asymmetric ground state of Ra223 and the spherical shell-model orbitals of Pb209 involved in the C14 decay are consistent with the experimental hindrance factors from the C14 fine structure except that the j15/2 orbital is more strongly populated experimentally than the calculations suggest.
