Abstract

The concept of “deformed nucleus” has become so firmly rooted in modern physics that it would not appear to be in need of any definition or improvement. Five years ago it was assumed that there were three regions of “complete” deformation with clearly pronounced boundaries: a region of light deformed nuclei (A ≅ 24), medium deformed nuclei (150 < A < 192) and heavy deformed nuclei (A > 226). In the succeeding years, however, an ever increasing number of nuclear states have been included in deformed states; this process is being intensified and will evidently be still further accelerated. At the same time, the inclusion of nuclei in the category of deformed nuclei is done on the basis of very diverse and sometimes debatable criteria; we shall later attempt to classify them but at first we shall consider the direction in which the number of deformed nuclear states is being or may be extended.
