Nuclear Reactions and Interaction of Neutrons and Matter

The collection comprises mainly articles dealing with research on nuclear, neutron- induced reactions and with the nonstationary neutron transfer in moderating media.

Some experi- mental methods of research on nuclear reactions are also considered.

The collection of articles has been written for physicists working in the field of nuclear physics, but may also be useful for scientists of other disciplines using the methods of nuclear physics in their research work.
