Abstract

The isotopic shifts in Er I and Er II spectra were investigated by means of a recording spectrometer with a Fabry-Perot interferometer. The experimental technique of measuring the shifts of the spectral lines consists of using monoisotopic sources of light and a photoelectric record of alternating interference patterns corresponding to the different isotopic components. The values of the relative shifts of 30 lines of erbium and the data of the deformation parametersβ of the nuclei of Er166 and Er168 were used for determining the intrinsic quadrupole moment of Er162. It follows then from the theory of the isotopic effect in the spectra of elements with deformed nuclei, that the value of the intrinsic quadrupole moment isQ 0(Er 162)=(7·25±0·30)× ×10−24 cm2.
