dc.typeAufsatz
dcterms.abstractThe approximations normally used in the calculation of the isomer shift are compared with the exact expressions using Dirac-Slater orbitals and a three-parameter Fermi-type nuclear charge distribution. The nonuniformity of the electronic density over the nuclear volume affects the results. Different choices of the nuclear surface thickness t and the radius c in the protonic density P_N (\gamma) also affects the isomer shift differently even though the values are chosen to yield a given value of \delta <r^2>. The change in the electronic charge density which is caused by the alteration of P_N (\gamma) in the ground state and excited state of the nucleus is discussed using two extrememodels and the possible influence on the observable isomer shift is estimated.eng
