- Аннотация: 7Li elastic scattering and the lithium-induced reaction of one-nucleon transfers from 10B(7Li,6Li)11B have been measured at ELAB(7Li) = 58 MeV using U-400 accelerator beam of the FLNR JINR, Dubna. Angular distribution for reaction 10B(7Li, 6Li)11B with excitation of the 3.56 MeV state (6Li∗)is presented for the first time. The “Finite Range Distorted Wave Born Approximation” (FRDWBA) analysis of the differential cross section of the 10B(7Li, 6Li)11B ground state (g.s.) transition and excited (Jπ =0+, T =1,E =3.56MeV)state of 6Li transition was performed. Phenomenological approach based on solving an approximate equation for the reaction form factor was used to determine its radial dependence and empirical values of asymptotic normalization coefficient (ANC). The obtained values of ANC for the 6Lig.s. and 6Li∗(3.56 MeV)states are in agreement with the literature ones. Comparison of the radial dependences of formfactors shows that the wave function of the 6Li nucleus in excited (Jπ =0+, T =1,E =3.56MeV) state has increased spatial dimension compared to the ground state. This result is an argument in favor of a halo existence in 6Li∗(3.56 MeV) state, while the question of a halo in 6Lig.s. still stays open.
