First estimation of the decay halftime limit based on the data measured during 4500 hours equals to T? ? 2,4 · 1021 years (68% C.L.). Angular distributions of the 13C+11B elastic and inelastic scattering were measured for the first time at Elab (11B) = 45 MeV in the full angular range for the transitions to the ground and excited states of the 13C and 11B nuclei. The data were analyzed within the optical model (OM) and coupled-reaction-channels method. The mechanism of the 13C+11B anomalous large angle scattering was studied. The isotopic effects in the elastic and inelastic scattering of 13C+11B and 12C+11B are discussed. The OM potential parameters for the 13C+11B elastic scattering and deformation parameters of 11B and 13C were deduced. Product Description popup.authors popup.nrat_date 2020-04-02 Close
