Summary:
Electromagnetic transition probabilities and static moments of excited nuclear states are known to be good probes of nuclear structure. Therefore, a systematic analysis of the large amount of existing experimental data for these observables is expected to provide valuable information about the respective isotopes. It is the purpose of this talk to show that a combined analysis of static magnetic moments of 2/sub 1//sup +/ states and B(E2) transition probabilities for even-even nuclei can be used to obtain effective numbers of valence nucleons. This kind of information is of particular interest in cases where subshell closures are found. For example, it is well known that for the transitional nuclei in the A = 150 region the Z = 64 subshell is active when the number of neutrons N < 90, but disappears for N greater than or equal to 90. A similar situation exists in the A = 100 region, where the Z = 38 subshell is active for N less than or equal to 58. In the following sections we present the method by which effective numbers of valence protons and neutrons can be deduced from B(E2) and g-factor data, and show applications of this method to the A = 150 and A = 100 transitional regions. Part of these results were recently published.
