“…[61]. In this approach, a connection between the physical origin of the Mössbauer isomer shift and the origin of the isotope shift of the electronic energy terms was explored [62,63]. The interaction with the nucleus of a finite volume results in the same energy shift of the electronic energy terms as for the nuclear terms.…”

“…This isotope shift arises from the difference of the nuclear masses of the isotopes and from the difference of the nuclear Coulomb field experienced by the atomic electrons involved in the transition. The latter contribution, historically referred to as volume effect, 1 is due to isotopic differences of the nuclear charge distributions of which the mean square eh arge radius <r 2 > enters into the volume effect calculation.…”

The isotope shift and hyperfine structure of the optical Sn resonance transition 5p 2 3 p 0 -+ 5p6s 3 P 1 at >..=286.3nm have been studied for 18 Sn nuclei including 2 isomers. Laser induced resonance fluorescence from a collimated atomic beam of tin was observed using a tunable cw dye Iaser .with frequency doubler. The electromagnetic nuclear moments and changes of the mean square charge radii of the nuclear charge distributions were determined. The results are discussed with respect to the information they provide on the nuclear structure of the nuclei investigated; they are compared with various theoretical models. DIE LASERSPEKTROSKOPISCHE BESTIMMUNG DER KERN-LADUNGS-RADIEN UND -MOMENTE VON ZINN-ATOMKERNEN I. I ntroductionThe energies of atomic transitions, in particular those associated with s electrons, alter slightly with the neutron number of the atomic nucleus. This isotope shift arises from the difference of the nuclear masses of the isotopes and from the difference of the nuclear Coulomb field experienced by the atomic electrons involved in the transition. The latter contribution, historically referred to as volume effect, 1 is due to isotopic differences of the nuclear charge distributions of which the mean square eh arge radius enters into the volume effect calculation.Effects of nuclear polarization associated with the interaction between atomic and nuclear states also give rise to isotope shifts, but this contribution is expected to be so small that it can be ignored for transitions of normal atoms. 2 In addition, the interaction of the nuclear magnetism and of nonspherical components of the nuclear charge distribution with the atomic electrons Iead to the weil known hyperfine splitting of atomic lines.Studies of these nuclear effects observed in atomic transitions are an important source of nuclear structure information, in particular about the systematics of nuclear charge radii and electromagnetic moments in long isotopic series. The renewed interest and may shed some light on pairing interactions. 13The present paper reports on Iaser spectroscopic measurements of the isotope shift and the hyperfine splitting in the 5p 2 3 P 0 -+ 5p6s 3 P 1 The experimental setup has been described elsewhere, 17we therefore restriet the description mainly to special features and alterations that were introduced for the tin experiments.The evaporation of the tin samples required temperatures of about 2100· K which are much higher than those used previously in the apparatus. This temperature is considerably higher than that one required for evaporation of bulk tin. The reason possibly is that the samples are so small that the tin atoms are spread over the crucible in low concentration which seems to bind them more strongly to its surface. Therefore a new heater of the electron bombardment type was developed. The anode is a vertically mounted tube made of high purity graphite. The crucibles are made of spectroscopically pure graphite so that practically no tin was detected with an empty crucible h...
