Electron scattering from sup 198 Hg and sup 204 Hg
This experiment is the first electron scattering study on mercury isotopes. Electron scattering from {sup 198}Hg and {sup 204}Hg has been performed at the NIKHEF-K Medium Energy Accelerator. Measured cross sections cover an effective momentum transfer range from 0.4 to 2.9 fm{sup {minus}1}. Elastic cross sections were determined for scattering from both isotopes. Cross section for inelastic excitations in {sup 198}Hg below 3 MeV were also determined. Measured cross sections were fit using DWBA phase shift codes to determine coefficients for Fourier-Bessel expansions of ground state and transition charge densities. Differences between the ground state charge densities of the two isotopes reveal the effect of the polarization of the proton core in response to the addition of neutrons. Spin and parity of several excited states of {sup 198}Hg were determined. Extracted transition densities of these states show their predominantly collective nature. Charge densities for members of the ground state rotational band were compared with axially symmetric Hartree-Fock and geometrical model predictions.
