ABSTRACT: Values of R, the radius of rotation of the rotating cluster,
are calculated from the energy of the lowest 2/sup +/ level
of even-even nuclei with the assumption that the cluster
consists of p/sup 2/ or n/sup 2/ respectively, for N or P
magic, and of a helion ( alpha ) for N or P differing from a
magic number by +or-2. The values as a function of A show a
zigzag course, which is correlated with the polyspheron
structure of the nuclei. If the mantle is not overcrowded
the rotating cluster moves within the mantle. When the
mantle becomes overcrowded the cluster glides over the
surface of the mantle and the value of R increases by one
spheron diameter, about 3.2 fm. At certain values of N a
change in structure of the nucleus occurs, with increase in
radius of the core by half a spheron diameter, permitting
the cluster to drop back into the mantle, with decrease in R
by half a spheron diameter (10 Refs.)
