    Muon transfer in dµ + H2 collisions (1999)

    Notes: Abstract The impact of excited state muon transfer in dµ + H2 collisions has been investigated. The formation of metastable pdμ* molecules and their subsequent decay into the pμ (1s) + d channel opens a transfer channel that is otherwise closed at the n=2 level. This mechanism enlarges the fraction of muons arriving to the ground state of the lighter isotope. The resulting ground state population P 1s pμ as function of deuterium concentration appears to be in qualitative agreement with recent measurements of the K α X-ray yield in H2/D2 mixtures.

    Excited states of muonic helium hydride ions and their possible impact on muon reactivation (1999)
    Springer
    Hyperfine interactions 118 (1999), S. 223-228 
    Details
    ISSN: 1572-9540
    Keywords: muonic helium hydride ; muon reactivation
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract Several previously unknown resonances of the μtμ helium hydride ion have been identified using a variational procedure. It is suggested that these resonances may form in αμ(1s)-TD(T2) scattering, for centre of mass collision energies in the range 8–10 keV. If the molecular complex [(αtμ)*dee]* is formed in a dissociative state (with respect to the α tμ-d coordinate), the dissociation energy may in part be transferred to the muonic degrees of freedom, opening the exit channel [(αtμ)*dee]* → tμ + α e + T, effectively amounting to muon transfer from α to t. We present a theoretical formulation of this novel and hypothetical mechanism for muon reactivation together with a numerical calculation of its cross-section for a special case.

    A configuration-interaction-oriented implementation of the complex coordinate method (1993)
    New York, NY : Wiley-Blackwell
    International Journal of Quantum Chemistry 46 (1993), S. 365-374

    ISSN: 0020-7608

    Notes: An implementation of the complex coordinate method is demonstrated that exploits a new technique for obtaining the matrix representation of the complex dilated Hamiltonian. The purpose is to make the complex coordinate method applicable together with standard numerical ab initio codes designed for large-scale calculations on many-electron atoms and/or molecules. No complex intergrals have to be calculated, and no changes of the standard codes are required even in the common case where the kinetic and potential energy components are not stored separately. Instead, two standard (real) CI calculations are used to generate the dilated (complex) CI matrix representation. The performance of the procedure is demonstrated in the context of the GAMESS program and applied to obtain the resonant structure of the Bethe surface pertinent to the absorption spectrum of the helium atom. © 1993 John Wiley & Sons, Inc.
