Direct determination of the atomic mass difference ofRe187andOs187for neutrino physics and cosmochronology

A set of 24 precise determinations of mass spectroscopic doublet spacings, including a new determination of the 176Hf35Cl – 174Hf37Cl mass difference, has been combined with nuclear reaction and decay Q values in a least squares adjustment of the atomic mass differences in the region 68 ≤ Z ≤ 72. The following quantities have been calculated for each nuclide: separation energies for the last neutron and last pair of neutrons (Sn, S2n), the neutron pairing energy (Pn), separation energies for the last proton and last pair of protons (Sp, S2p), the proton pairing energy (Pp), Q values for α and β− decays, and the mass defect. The systematic variations of these quantities with N and Z are discussed.

AbstractWe propose a two-lattice method for direct determination of the recoilless fraction using a single room-temperature transmission Mössbauer measurement. The method is first demonstrated for the case of iron and metallic glass two-foil system and is next generalized for the case of physical mixtures of two powders. We further apply this method to determine the recoilless fraction of hematite and magnetite particles. Finally, we provide direct measurement of the recoilless fraction in nanohematite and nanomagnetite with an average particle size of 19 nm.
