Abstract |
An exotic type of decay - cluster emission - was observed in actinides
region in 1980's [1, 2, 3]. In this process a light nucleus, but heavier then
alpha particle is emitted, while the heavy mass residue is close to doubly
magic lead in all observed cases. Microscopic description of this phenomenon
treated as a very asymmetric fission has been successfully performed within
HFB model with Gogny interactions D1S [4]. The fission valley on the
potential energy surface has been found and fission fragments have been
identified as cluster radioactivity products. Recently the characteristic very
asymmetric fission valleys have been also found in some super-heavy nuclei.
It has been shown that cluster radioactivity plays a nonnegligible role in this
part of nuclear chart [5].\newline
