The angular distributions of elastic scattering $^{7}$Li, as well the lithium-induced reaction one-nucleon transfers $^{10}$B($^{7}$Li,$^{6}$Li)$^{11}$B were measured at $E_{lab}$ = 58 MeV. Experiment was done using U-400 accelerator beam FLNR JINR, Dubna. Angular distribution for with excitation 3.56 MeV state ($^{6}$Li*) is present first time. DWBA analysis differential cross section ground (g.s.) transition and excited ($J^\pi$ 0$^+$, $T$ 1, $E$ MeV) $^{6}$Li performed. optical model potentials obtained by fitting data evaluating parameters output channels. Phenomenological approaching based on solving an approximate equation form factor used to determine its radial dependence empirical values asymptotic normalization coefficient (ANC). Obtained ANCs $^{6}$Li$_\text{g.s.}$ $^{6}$Li*(3.56 states are similar literature one. Comparison dependences factors shows that wave function nucleus in has increased spatial dimension compared state, both cases some larger size than $^{11}$B $^{10}$B. Within framework our analysis, we can confirm radius state. This result argument favor a halo existence while question still leaves open.
