In this group of subjects we would like to develop (or significantly improve)
the methods of solving the nuclear problems, especially those corresponding to
nuclear phenomena studied in state-of-the-art experiments. The motivation of
this research consists in observing that the theoretical description of several
effects is not sufficiently powerful in view of the new precision and/or of
the actual abundance of the experimental information. We envisage therefore
either new important extensions in the existing methods and/or preparation
of new approaches.
