Low and Intermediate Energy Low and Intermediate Energy PhysicsPhysics

The future research programme in the field of low and intermediate energy

physics will arise from the modern trends in this field with the utilization of

experimental facilities and nuclear physics techniques that have been

created in the DLNP up to now.

The fundamental research will be concentrated on the following topics:

Non-accelerator physics The experimental investigation of neutrino properties via

nuclear spectroscopic methods (NEMO, TGV, SuperNEMO, G&M and GEMMA)

Searching for the dark matter in the Universe (DM-GTF, EDELWEISS-2)

Experimental investigation of the space symmetry in nuclear semi-leptonic processes (AnCor)

Accelerator physics Experimental investigation of the muonic catalysis on

nuclear fission reactions (TRITON) Systematic experimental investigation of decay

characteristics of radioactive nuclides and nuclear structures (YASNAPP-2 ISOL)

Low and Intermediate Energy Low and Intermediate Energy PhysicsPhysics

The applied research will be mainly concentrated on improvement and further development of proton and heavy ion therapy as well as on both innovative nuclear energy systems and waste transmutation issues.

Nuclear TheoryThe 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.
