21. Nuclear Theory The scientific programme of BLTP in the field of nuclear theory will be concern with theoretical understanding of the nuclear many-body system. Many essential questions will be addressed to the nuclear structure and dynamics, nuclear astrophysics. Much of what we know about nuclei, their structure and dynamics comes from nuclear reactions. Since many-body reaction models do not exist, a synthesis between microscopic structure theory and reaction must be made to incorporated and imbed the important few-body and many-body correlations into the reaction matrix elements. The study of symmetries in nuclei and how these symmetries can be broken will give guidelines to how to unify the large body of present knowledge. In many of the astrophysical models nuclear theory has to bridge a gap between experimental data and astrophysical application. The strategy of the BLTP is close collaboration with the JINR experimental groups.
