The general achievements of the present collaboration are: qualitative and quantitative description of the series of microscopic events induced by muons in mixtures of hydrogen isotopes, in particular processes entering the chain of µCF and leading to fusion reactions in muonic molecules acquisition of data needed in the feasibility studies of a µCF-based intense (~ 1014n/cm²s) neutron generator broadening of the scientific potential of µCF to the contact areas of astrophysics, particle physics and fusion energy research the essential and most technical part of the collaboration involved the development of effective methods of solution of the Coulomb three-body problem, of importance for muonic and pionic physics and for the related investigations of weak and strong interactions. The specific results are: Calculation of the structure and properties of muonic molecules. Development of theoretical methods for solving the Coulomb three-body problem, including its bound, resonant and scattering states, with emphasis on characteristics relevant for µCF such as energy levels, life times and conditional particle densities. Calculation of the cross-sections for collisions involving mesic atoms in the ground and excited states. Treatlment of the interplay between the nuclear, weak and coulombic forces. Development of the macroscopic description of muonic processes in form of kinetic models and codes including excited state muon chemistry and physics of µCF. The results obtained by the present collaboration are of crucial importance for the analysis of µCF experiments at PSI. They are also necessary for the implementation and for the analysis of the currently ongoing experiment in Dubna on muon catalysed fusion in pure deuterium and H/D/T mixtures. Another application area of the data created by the present collaboration is the feasibility study of the µCF-based, intense fusion neutron generator. In a broader perspective, the results obtained by the present collaboration are applicable for solving various problems in atomic and molecular physics, in the physics of weak interactions, in thermonuclear and muon catalysed fusion, low energy nuclear physics and astrophysics. The results have been presented as scientific publications in refereed international journal and in the form of lectures and presentations at scientific conferences.
