• Heavy ion beam. • Peripheral proton transfer • Modified distorted wave Born approximation (MDWBA) • Asymptotic normalization coefficient (ANC) • Astrophysical S -factor. The 11 B( 10 B, 9 Be) 12 C reaction was studied at the energy of 41.3 MeV with transitions to the ground (0 + ) and low-lying excited 4.44 MeV (2 + ) and 9.64 MeV (3 − ) states of 12 C nucleus. The analysis of the measured angular distributions was carried out using a modified distorted wave (MDWBA) method, assuming a one-step proton transfer mechanism. It was shown that at small angles (in the region of the main diffraction maximum) this reaction occurs on the nuclear surface with the dominance of a one-step process. This made possible to determine the values of asymptotic normalization coefficients (ANC) for 11 B + p → 12 C. The squared ANCs equal to 322 ± 76 fm −1 , 32.8 ± 8.4 fm −1 and 1.26 ± 0.44 fm −1 for 0 + , 2 + and 3 − states of the 12 C nucleus respectively were obtained. These values were used to take into account the contribution of the direct process in the calculation of astrophysical S -factors for the radiative capture of a proton by the 11 B nucleus at astrophysical energies.
