J. E. Thun's 51 research works with citations and reads, including: Alpha-gamma Angular Correlation and Hyperfine Interaction in the Decay of Cf. Theoretical internal conversion data had become available to such an extent that electron -gamma direct­ ional correlations became an important tool in the investigation of nuclear structure: in a large number of cases it is more advantageous to study electron -gamma corre­ lations instead of the commonly measured gamma -gamma directional. A study of such perturbed directional correlation (PDC) has the potential to provide information on protein-metal interactions. The use of a radioactive nucleus as a rotational tracer to label macromolecules offers the possibility of obtaining information on protein structure with the sensitivity and instrumental simplicity of radioactive Cited by: 6.   Directional gamma-gamma correlations of the strong – keV and of the weak – keV cascade transitions in the decay ofgLu have been measured. The correlation coefficientsA 22=−± of the strong andA 22=−± of the weak cascade have been determined. The mixing ratioE2/M1 of −± for the keV transition and theM2/E1 of .

Also discussed are the hyperfine interactions of light interstitial impurities in ferromagnetic Fe and Ni, as well as in fcc and bcc non-magnetic metals. For these spin β -ray correlation experiments, it is emphasized that the technical developments and improvements of the nuclear spin control by NMR and the production of polarization in the. Correlation between Q and decay half-life Investigation of decay by Rutherford’s students and collaborators Hans Geiger and John M. Nuttall lead to the observation of correlation between the Q value and decay half-life ln(˝) = A+ B p Q (1) As realized by Gorge Gamow calculations based on the tunnelling result in a nearly similar correlation.   A time differential directional correlation method using a slow-fast coincidence setup consisting of four BaF2 detectors was applied to measure the an.

The 'goIrFe hyperfine interaction The magnetic hyperfine interaction Hamiltonian is HM = -,uBm/I. To this we have added a term with the form of equation (2) to account for the electric quadrupole interaction at the iridium sites arising in second order from the spin-orbit interaction in iridium in iron (Aiga and Itoh , Johnston and Stone. Publisher Summary. This chapter discusses the experimental and theoretical particle parameters for L electrons. During directional correlation studies, conversion electrons that were involved have achieved increased importance not only because they make correlation measurements in a complex decay feasible but also because of the information gained about the conversion process itself. The hyperfine interactions of Cd in GaP, GaAs, GaSb, AlSb, and InSb were determined by means of the time-differential perturbed-angular-correlation technique. The hyperfine interaction has often been described as the bridge between atomic physics and nuclear physics. On the one hand it enables us to study important nuclear phenomena which only manifest themselves in the strong internal fields originating from the surrounding electrons and on the other hand it enables us to study properties of the atomic system or of condensed matter using nuclear.
