    Notes: Abstract The 5d 26s 2 3 F 2 ground state of177Hf,179Hf and180Hf has been studied using the atomic beam magnetic resonance method. The atomic beam was produced by an universal evaporation technique described in a previous paper. The results are180Hfg j (3 F 2)=0.695812 (10)177Hf Δv(3 F 2;F=11/2↔F=9/2)=991.7917 (10) MHz Δv(3 F 2;F=9/2↔F=7/2)=477.0081 (10) MHz Δv(3 F 2;F=7/2↔F=5/2)=162.8890 (10) MHz179HfΔv(3 F 2;F=13/2↔F=11/2)=82.1320 (10) MHz Δv(3 F 2;F=11/2↔F=9/2)=392.8498 (10) MHz. The magnetic dipole and electric quadrupole moments of the177Hf and179Hf nuclear ground states as calculated from these hyperfine structure measurements are the following: μ(177)=0.75(8)μ k , Q(177)=4.34 (65) barns μ(179)=−0.61 (6)μ k , Q(179)=4.90 (75) barns.

    Notes: Abstract Using the atomic beam magnetic resonance method the experimental hyperfine structure data of the 5d 26s 2 3 F 2 ground state of177Hf and179Hf described in a previous paper [1] have been completed. After applying corrections due to perturbations by other fine structure levels of the configuration 5d 26s 2 we got the following multipole interaction constants: $$\begin{gathered} ^{177} Hf:A = 113.43314 (7) MHz B = 624.3293 (13) MHz \hfill \\ C = 0.27 (18) KHz D = 0.045 (40) KHz \hfill \\ ^{179} Hf: A = - 71.42891 (9) MHz B = 705.5181 (24) MHz \hfill \\ C = - 0.43 (20) MHz D = 0.07 (6) KHz. \hfill \\ \end{gathered} $$ By measuring rf transitions at magnetic fields between 1100 and 1550 Gauss the nuclear ground state magnetic dipole moments were determined. The results are: $$\mu _I (^{177} Hf) = 0.7836 (6) \mu _N , \mu _I (^{179} Hf) = - 0.6329 (13) \mu _N $$ (uncorrected for diamagnetic shielding).

    Notes: Abstract The hyperfine interaction constantsA andB of six low-lying metastable fine structure states of the two iridium isotopes191Ir and193Ir and the electronicg-factors of these levels have been measured using the atomic-beam magnetic-resonance method. From the values of the magnetic-dipole interaction constantsA, corrected for off-diagonal perturbations, we extracted the hyperfine anomaly of a pure 6s-electron state:191 Δ s 193 =0.64(7)%. Using nonrelativistic approximations for the effective radial parameters the nuclear electric-quadrupole moments were obtained:Q(191Ir) = 0.81(21)b,Q(193Ir)=0.73(19)b

Using intermediate coupling wave functions derived for the configurations (5d+6s)5 the hyperfine structure data of six low-lying metastable states have been analyzed with respect to the effective operator formalism. The effective radial parameters for the magnetic dipole and electric quadrupole interactions are determined from these measurements and compared with relativistic calculations. The value obtained for the spectroscopic quadrupole moment of the181Ta nuclear ground state is Qhfs=3.44(17) barn (uncorrected for configuration interaction effects).

    Notes: Abstract The hyperfine structure of the ground state 4d 5 5s 7 S 3 of95Mo and97Mo has been measured by the atomic beam magnetic resonance technique with the following results:95Mo:A=−208.582060(10)MHz,B=37.050 (100) kHzC=−30 (10) Hz,D=−3 (3) Hz97Mo:A=− 212.980930 (10) MHz,B−69.990(140)kHzC=−5 (10) Hz,D=0 (3) Hz. After application of corrections calculated according to second order perturbation theory, the hyperfine structure constants became:95Mo: Ac=−208.582560(290)MHz,B c =16.920(4300)kHzC c=−30(270) Hz,D c =− 3 (50) Hz97Mo: Ac=212.981450(300) MHz,B c =−90.780(4400)kHzC c=−6(270) Hz,D c =0 (50) Hz. With the known ratio ofg I(95Mo)/g I(97Mo) [1] a calculation of the hyperfine anomaly yields:95 Δ 97=−0.01009(17)%. The ratio of the uncorrectedB factors isB(97Mo)/B(95Mo)=−1.8890(47). Because of the relatively large effects of second order hyperfine structure, the ratio of the correctedBfactors differs considerably from the ratio of the uncorrectedB factors. From the correctedB factors the electric quadrupole moments may be evaluated by means of calculated radial integrals [2]. The results are:Q (95Mo)=−0.019(12)barns,Q(97Mo)=0.102(39)barns.

    Hyperfine structure and isotope shift of high-lying metastable states of rhenium (1982)

    Notes: Abstract Fourteen transitions in ReI, starting from high-lying metastable states belonging to the configurations (5d+6s)7, have been studied by laser-induced fluorescence in a collimated atomic beam, and accurate values for the isotope shifts in these transitions as well as for the hyperfine structure constants of 13 metastable and 9 excited states have been obtained. In addition, high precision measurements of the hyperfine structure of the states 5d 5 6s 2 4 D 7/2 and 5d 6 6s 6 D 1/2, 3/2, 5/2, 9/2 have been performed using the atomic beam magnetic resonance technique coupled with laser-induced state-selective detection of metastable atoms. The analysis of the hyperfine structure data yields experimental evidence for far configuration mixing effects on the off-diagonal spin-dipole matrix elements. The phenomenological interpretation of the isotope shifts shows the significance of off-diagonal field-shift effects.
