    6Li break-up effect on elastic and inelastic scattering of6Li +6Li at 156 MeV (1985)

    Notes: Abstract The elastic and inelastic scattering of 156 MeV6Li projectiles from6Li is studied experimentally and theoretically. The experimental differential cross sections are analyzed by the method of coupled discretized continuum channels in which resonant and non-resonant break-up states of6Li are taken into account explicitly. The measured cross sections are simultaneously reproduced quite well by the calculations. Coupling effects of the break-up states are found to play an important role for the scattering.

    Notes: Abstract Recently, the muonic three-body systemdtμ, has aroused considerable attention in relation to the realization of a useful muon-catalyzed fusion [1, 2]. This bound system must be solved up to 6 digits in energy to establish the muon catalyzed fusion process. We applied the ATMS method [3] and the coupled-channel method [4] to the Coulomb three-body system and obtained the detailed information on the energy levels and the wave functions of the bound states. Further we investigated the effect of the nuclear interaction on the fusion rate in the bound states [5] and developed a formalism to calculate the muon sticking to4He [6]. In this paper we report the results obtained in our collaborations: Figure 2 shows up our main results.

    Notes: Abstract Energy shifts in the shallowest level of the muonic moleculedtμ are estimated by using an accurate wave function of the point-charge three-body system which gives ε 11 0 = −660.3 meV. Contributions of nuclear finite size, vacuum polarization, relativistic effect and internuclear interaction are evaluated to be +10.4 meV, +17.2 meV, +0.9 meV and ∼ +10−4 meV, respectively. These corrections to ε 11 0 amount to 28.5 meV, which is significantly different from the corresponding value 20.6 meV of the Soviet group, with serious dependence on the dtμ, formation rate.

    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.
