EXPERIMENTAL METHODS FOR INVESTIGATION OF NUCLEAR REACTIONS WITH SECONDARY RADIOACTIVE BEAMS IN ENERGY RANGE 1 - 60 MeV/amu

The plant operating in the condition of the "labelled atoms" i.e. selection of the radioactive beam ions according to the mass and energy has been created. That permitted to use the "thick" target in the experiments with exotic ions with in-event indication of the interactions. The elastic scattering of the radioactive *996He, *999Li, *997Be, *998B nuclei on the carbon and also the fusion-fission and fusion-evaporation reactions under action of the *994*99,*996He nuclei have been investigated. It has been determined that the fission reaction of *992*990*999Bi(*996He, f) is more sesitive to the display of the neutron excess in the *996He nucleus than the evaporation reaction of the *992*990*999Bi(*996, 4n)*992*991*991At neutrons. The supposition about existence of the neutron "fur-coat" (skin-effect) in the *996He nucleus displaying as a static and/or dynamic deformation of the nuclear has been made from analysis of the dataAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
