“…As observed earlier and seen from Table 2, the isotope shift in D 1 line is larger than in D 2 line which is contrary to expectation and unlike that in the case of Ba + [15], Fr [16] and Pb + [17]. According to relativistic Dirac-Fock calculations (without configuration interaction) reported by Torbohm et al [18], the ratio of field shift in D 1 line and D 2 line should be 0.967.…”

Isotope shift ∆σ( 172 Yb − 176 Yb) has been measured in 79 classified lines of Yb II in the region 3225-6155Å. Earlier studies provide isotope shift data in just six lines of Yb II. Term isotope shift ∆T ( 172 Yb-176 Yb) have been evaluated for 38 even and 30 odd parity levels of Yb II, using the present isotope shift data. The ∆T values have been discussed and correlated with the purity of the configuration assigned to an energy level, which enabled to check the reported eigenvector percentages of different configurations for some of the levels of Yb II. ∆T values of different levels resulting from J I L II couplings are also discussed.

“…Optical measurements of the 6P, /2-6P3/2 M1 finestructure transition at 710 nm in lead ions by conventional spectroscopy [1] and by pulsed laser excitation in an ion trap [2] have results in values for the ground-state hyperfine-splitting (hfs} constant of the 207 mass isotope, which do not agree within the quoted limits of error. To clarify the situation we have performed narrow-band cw laser excitation on Pb+ stored in a rf quadropole trap with proper calibration of the laser frequency.…”

The 683/2 6P1/2 magnetic dipole resonance transition in Pb has been observed by cw laser excitation of an ion cloud stored in a Paul trap and subsequent detection of the fluorescence radiation. From the hyperfine-structure splitting of the spectrum we determine the A factor for the ground state, 2 (Pl/2 ) = 12.967( 13) GHz and the excited state, 3 (P3/2 ) =0.580(3) GHz. From a contamination of Pb in our sample we derived the 'Pb+-Pb+ isotope shift [b v=311(14}MHz]. A small electric quadrupole admixture giving rise to a EF=2 component in the spectrum has been determined to be 6.4(0.5)% of the total transition amplitude.

ABSTRACT:The fine structure of the even-parity low configurations has been reanalyzed by simultaneous parameterization of the one-and two-body interactions for the model space (4d þ 5s) 3 . Using the calculated eigenfunctions, the magnetic-dipole A hyperfine constants for the whole 37 existing levels of the model space were predicted and compared partially to those obtained using relativistic configuration-interaction approach. Moreover, volume shifts (VS) and specific mass shifts (SMS) of numerous configurations of singly ionised zirconium are deduced by means of ab initio estimates combined with a few experimental isotope shift data available in literature: VS (4d 1 5s 2 )
