Abstract: One possible explanation for the anomalous isotope shifts of 183,185Hg is the sudden occurrence of permanent quadrupole deformations. The α-particle decay of 25 s 188Pb, however, does not show any rotational fine structure. It is interesting to consider the possibility that the nuclei 183–185Hg have “bubble” shape.
