We review our method of calculation, Gaussian Expansion Method (GEM), for bound and
scattering states of few-body systems. The method was proposed in 1988 and has been …

A new variational approach to muonic molecules is proposed. The total three-body wave
function is expanded in terms of basis functions spanned over the three rearrangement …

The current state of research on muon catalysis is presented. Means of possibly using this
phenomenon for the production of nuclear energy and neutrons are discussed, as is the role …

The total cross sections of the elastic, spin-flip, and charge-exchange processes for the
scattering of muonic hydrogen isotope atoms (pμ, dμ, tμ) in the ground state on hydrogen …

Variational calculations of energy levels, of ϵJv and λ-factors of weakly bound rotational-
vibrational states (J= 1, v= 1) of the mesic molecules ddμ and dtμ, which are of main interest …

This volume contains two major articles, one providing a historical retrosp-tive of one of the
great triumphs of nuclear physics in the twentieth century and the other providing a didactic …

Methods of computational physics developed at JINR for investigation of models of complex
physical processes in different fields of theoretical physics are considered. A general …

We present variational calculations of the energy levels of the td μ ion relevant for muon-
catalyzed fusion. We used very large generalized Hylleraas basis sets. For all the levels the …

We present a detailed theoretical analysis of experimental rates for ddμ molecular formation
and dμ hyperfine transitions at temperatures 25.5–150 K, which were reported by Zmeskal et …

The quasiresonant mechanism of mesic molecule formation, in triple collisions of the type
tμ+ D2+ D2→[(dtμ) d2e] ν∗+ D'2 is considered. It is shown that at small resonance defects …
