The basic assumption of nuclear shell model is that from the standpoint of any one nucleon, the forces between it and all the other nucleons can be represented by a potential well. Given the parameters of this well, the locations of all shell model states should be readily calculable. However, after many years of such calculations it has become clear that there is no simple set of well parameters that can accurately fit even a small fraction of the data. It is thus important to accumulate data on the location of these states in order to find what effects are important in determining their location. These data are also very useful since they are inputs in a great many calculations in nuclear structure theory.
