    Notes: Abstract From Mössbauer effect measurements the magnetic momentμ=(+1.80±0.08) nm of the 83.4 keV rotational state of153Eu and the ratio of the changes of the mean square charge radiiΔ〈r 2〉 (153Eu, 83 keV)/Δ〈r 2〉 (153Eu, 103 keV)=+0.025±0.008 were determined. The results are interpreted on the basis of mixing of rotational bands by the Coriolis force.

    Notes: Abstract The Mössbauer effect of theγ rays from the 74.5 keV state of Dy161 and the 80.7 keV state of Dy162 has been investigated. From hyperfine splitting patterns the magnetic moments μ(75 keV)=−(0.39±0.04) nm, μ(81 keV)=+(0.74±0.08) nm and the quadrupole momentQ(75 keV)=+(1.4±0.2)b have been determined. For the odd neutron nucleus Dy161 an effective spin g factorg s, eff=0.76 gs, free is deduced for the 75 keV level.

    Notes: Abstract γ-ray spectroscopic techniques have been applied to measure properties of excited states (E *〈2MeV) in210Pb,212Po, and213At after populating these neutron rich (N=128) nuclei via18O induced few-nucleon transfer reactions on208Pb and209Bi targets. In212Po an isomeric state is located atE *=1,477 keV with a halflife oft 1/2=14.7±0.3 ns. This state is interpreted to be the 8+ yrast level which decays to the ground state via the measured $$8^ + \left( {121.1 keV} \right)6^ + \left( {223.3 keV} \right)4^ + \left( {405.1 keV} \right)2^ + \left( {727.8 keV} \right)0^ + $$ γ-cascade.α-decay (E α≈10.2 MeV) of the isomer is also observed. In210Pb the time spectra for members of the 4+ (297.8keV) 2+ (799.4keV)0+ γ-cascade show a delayed component with a halflife oft 1/2=152±13 ns which is attributed to the known 8+ yrast state atE *=1.27 MeV. For213At first results on theγ-decay of excited states are presented.

    Isomerieverschiebung im Eu151 (1965)

    Topics: Physics
    Notes: Abstract The isomer shift of the 21.7 keVγ transition in Eu151 has been studied for various divalent and trivalent europium compounds using the Mössbauer technique. Theγ energy is lower by up to 1.1·10−6 eV in divalent compounds than in trivalent compounds. Using data from atomic spectroscopy it is estimated that the electron density at the nucleus is larger by about 1.9·1026cm−3 for the configuration 4f 6 than for 4f 7 due to different shielding of thes 2 shells. The difference of the mean square radii of the 21.7 keV state and the ground state is thenδ〈r2〉=+0.03 fm2. The measured isomer shift between trivalent and metallic europium and the relatives-electron densities in the rare earth metals measured by the positron annihilation rates are used to establish a calibration scheme for isomer shifts in rare earth metals. This calibration scheme is used to deduce a changeδ〈r 2〉=+0.0055 fm2 between the 26 keV state and the ground state of Dy161.

    Mössbauer effect and magnetic moment of the 75.9 keV level in Yb171 (1967)

    Notes: Abstract The Mössbauer effect of the second excited state of theK=1/2 rotational band in Yb171 at 75.9 keV withI=5/2 was studied to determine its magnetic moment μ=(1.01±0.01)nm. This value agrees well with the one predicted by the previously determined magnetic parameters of theK=1/2 rotational band, confirming the adiabatic separation of intrinsic and rotational wave functions.

    Notes: Abstract The hyperfine Splitting of the 80.6-keVγ transition in Er166 has been measured in erbium metal between 4.2 °K and 40 °K using the Mössbauer effect. There is evidence for a unique magnetic field and electric fieldgradient at all nuclei in erbium metal. The magnetic field decreases from (7.55±0.20)·106 Oe at 4.2 °K to (6.10±0.40)·106 Oe at 40 °K. Extrapolation to 0 °K yieldsH (0 °K)=(7.60±0.20)·106 Oe. The quadrupole interaction energy for the 80.6-keV state iseQ V Z′Z′/4=(0.95±0.20)·10−6 eV at 4.2 °K. These results are discussed and compared with other measurements.

    Notes: Abstract The hyperfine splitting and isomer shift of the 73 keV γ transition in Ir193 was measured in the intermetallic compounds SmIr2, GdIr2, TbIr2, DyIr2, HoIr2, and ErIr2 using the Mössbauer effect. The electric field gradients, the electron densities, and the magnetic fields at the Ir nuclei were deduced from these experiments. An extensive discussion of the internal magnetic fields is given in terms of an empirical model.

    Notes: Abstract The 69.6-keV level with spin 5/2− in189Os was investigated by the recoilless resonance absorption technique. Its magnetic moment was found to beμ (5/2)=(0.977±0.014)μ N. From the measured ratio of the excited and ground-state electric quadrupole moments,Q(5/2)/Q(3/2)=−0.79±0.09, the excited-state quadrupole momentQ(5/2)=−(0.72±0.11)b could be derived. TheE2/M1 mixing parameter of the 69.6-keV ground-state transition was found to beδ=+0.69±0.10. The results are interpreted in terms of two low-energy rotational bands with strong Coriolis mixing.

    Notes: Abstract Isomer shifts of the 81.0 keVγ-transition in133Cs have been measured by the Mössbauer technique for eight ionic Cs compounds, and for the intermetallic compound CsBi2. The source was133Ba in CaF2. The shifts, relative to CsCl, range from −1.4 · 10−8 eV for CsNO3 to +1.6 · 10−8 eV for CsBi2. The difference in electron density at the Cs nucleus between CsBi2 and CsNO3 is discussed using chemical bonding arguments. For the Cs halides, this difference is estimated from the overlap of outer electron shells in the lattices. A relative change of the mean square charge radiusδ〈r 2〉/〈r 2〉=+2 · 10−4 is derived.
