Description

The form factor for excitation of the 1+ state at 3.48 MeV in 88Sr by inelastic electron scattering has been measured for momentum transfers q = 0.24-0.62 fm-1. Neither its magnitude nor shape can be described employing the best available nuclear wave functions. We demonstrate with a schematic model that the observed reduction of the form factor may be understood by taking into account a renormalization of the M1-operator due to virtual Δ-hole excitations.
