    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.

    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.
