    Isotope dependence of particle-decay rates of muonic molecular ions (d3,4Heμ) J=1 below (dμ)1s-3,4He threshold (1993)

    Notes: Abstract Rates of particle-emitting decay of the resonant state of the muonic molecular ion (dHeμ) J=1 lying below the (dμ)1s-He threshold can decay to the d-Heμ scattering state. The resonant state is estimated by scattering calculations with the non-adiabatic coupled-rearrangement-channel method. Strong isotope dependence of the decay rates of (d3Heμ) J=1 and (d4Heμ) J=1 is predicted, though the calculated radiative decay rates of the states are almost the same. In (d3Heμ) J=1, the particle decay width is three times larger than the radiative decay width, while the two types of decay widths are almost the same in (d4Heμ) J=1. This results in a strong hindrance of the branching ratio of the radiative decay of (d3Heμ) J=1 compared with the case of (d4Heμ) J=1. This is consistent with a recent observation of the radiative decay of the two molecular states.

    Non-adiabatic calculation of muonic atom-nucleus collisions (1993)

    Notes: Abstract In order to calculate the cross sections of the muonic atom-nucleus collisions, we have proposed a precise numerical method, a non-adiabatic coupled-rearrangement-channel method with the use of the Jacobian coordinates for the three-body system in the whole space. The scattering boundary condition is correctly imposed along the coordinates; this method does not suffer from the well known defects of the method of adiabatic representation. We applied our method to the muonic atom-nucleus collisions for an incident c.m. energies of 0.001–100 eV.

    Energy shift in (dtμ)e due to the finite size of the muonic molecular ion (dtμ)+ (1992)

    Notes: Abstract The energy shift due to the presence of the extended (dtμ)11 pseudonucleus (in its first excited state with one unit of angular momentum) in the quasihydrogenlike system (dtμ)11 e 1s is estimated using perturbation theory up to second order with two choices of zeroth order electron wavefunctions. The energy shift is found to be 0.50 meV using pure Coulomb electron wavefunctions and 0.58 meV using electron wavefunctions calculated with a potential modified to take partial account of the finite size of (dtμ)11. In both cases, the perturbation Hamiltonian is expanded in multipoles, retaining terms up to and including octupole terms.
