Isotopic Differences in the Charge Distribution of Even Molybdenum Isotopes from Elastic Electron Scattering

Elastic-electron-scattering cross sections for ${}_{}{}^{92,94,96,98,100}{}_{}{}^{}\mathrm{Mo}$ in an effective momentum transfer range of 0.6-2.1 ${\mathrm{fm}}^{-1\mathrm{}}$ are analyzed in a practically model-independent way, using a Fourier-Bessel expansion for the charge distribution. The ratios of cross sections of neighboring isotopes yield differences of charge distributions, which exhibit pronounced shell effects.
