    Double differential cross sections for electron ejection from helium by fast protons.
    (Australian Atomic Energy Commission, 1985-12) Gibson, DK; Reid, ID
    Measurements of the angular and energy distributions of electrons ejected from helium atoms by protons with energies between 20 and 100 keV are presented in tabular and graphical form. The electron energy range is between 5 and 100 eV and the angular range is between 0 and 100 degrees. The distributions have been converted to double differential cross sections by normalisation against other published data. An analysis of the accuracy of the results is presented.

    Double differential cross sections for electrons ejected from H2, O2, N2, CO2, CH4, H2O and Ar by 50 KeV protons.
    (Australian Atomic Energy Commission, 1987-04) Gibson, DK; Reid, ID
    Tabulated values of double differential cross section measurements are presented for electrons ejected from H2, O2, N2, CO2, CH4, H2O and Ar by 50 keV protons. The angular range extends from 0 to 100 deg and the electron energy from 5 to 150 eV.

    Muon implantation of meltallocenes: ferrocene
    (Wiley-VCH Verlag Berlin, 2006-06-18) Jayasooriya, UA; Grinter, R; Hubbard, PL; Aston, GM; Stride, JA; Hopkins, GA; Camus, L; Reid, ID; Cottrell, SP; Cox, SFJ
    Muon Spin Relaxation and Avoided Level Crossing (ALC) measurements of ferrocene are reported. The main features observed are five high field resonances in the ALC spectrum at about 3.26, 2.44, 2.04, 1.19 and 1.17 T, for the low-temperature phase at 18 K. The high-temperature phase at 295 K shows that only the last feature shifted down to about 0.49 T and a muon spin relaxation peak at about 0.106 T which approaches zero field when reaching the phase transition temperature of 164 K. A model involving three muoniated radicals, two with muonium addition to the cyclopentadienyl ring and the other to the metal atom, is postulated to rationalise these observations. A theoretical treatment involving spin-orbit coupling is found to be required to understand the Fe-Mu adduct, where an interesting interplay between the ferrocene ring dynamics and the spin-orbit coupling of the unpaired electron is shown to be important. The limiting temperature above which the full effect of spin-orbit interaction is observable in the SR spectra of ferrocene was estimated to be 584 K. Correlation time for the ring rotation dynamics of the Fe-Mu radical at this temperature is 3.2 ps. Estimated electron g values and the changes in zero-field splittings for this temperature range are also reported. © 2006, Wiley-VCH Verlag Berlin
