Abstract
The number of discrete rotational bands in the nucleus 168Yb is
obtained by a fluctuation analysis of the rotational ridge structure in double
and triple coincidence matrices. The data are compared with cranked
shell model calculations including a surface delta interaction. It is found
that the number of calculated bands strongly depends on the interaction
strength V0, and agreement between data and calculations supports the
standard value V0=27.5/A MeV.
