Boson densities in the germanium isotopes and inelastic electron scattering.

The collective properties of /sup 70,72,74,76/Ge have been explored through the measurement of the transition charge densities of the first two 2/sup +/ states up to a momentum transfer of 3.0 fm/sup -1/. Their spatial structure and their apparently anomalous behavior are readily explained in the framework of the interacting boson model.
