Description
Three approaches to the measurement of a rare alpha decaying
products produced in heavy-ion induced nuclear reactions are
described. One is based on a chemical extraction and following
deposition of the nuclides under investigation onto the surface of
the detector, whereas the second one is associated with long –lived
products implanted into silicon detectors by using the
electromagnetic separation technique. The third approach relates
with an application of real-time mode detection of correlated energy-
time-position recoil-alpha sequences from 48Ca induced nuclear
reactions with actinide targets, like 242, 244Pu, 245,248Cm, 239Am
and 249Cf [1-3]. Namely with this technique it has became possible
to provide a radical suppression of backgrounds in the full fusion
(3-5n) reactions aimed to the synthesis of super heavy elements with
Z=113-116.
