Determination of the transition charge densities of the low-lying 2+ states in 34S

The transition densities of the 0+ → 21+ and 0+ → 22+ transitions in 34S have been determined by an inelastic electron-scattering experiment covering a momentum transfer range 0.5 fm−1 < q < 2.5 fm−1. The cross sections were analysed model-independently by a Fourier-Bessel expansion. The resulting B(E2) values are in good agreement with adopted values from previous experiments. The deduced transition radii follow the systematics of E2 transitions. Shell-model calculations predict the form factor of the first 2+ state reasonably while they do not give the correct position of the diffraction minimum for the 22+ state.
