The differential cross sections for the reactions {sup 9}Be({sup 10}B,{sup 10}B){sup 9}Be and {sup 9}Be({sup 10}B,{sup 9}Be){sup 10} B have been measured at an incident energy of 100 MeV. The elastic scattering data have been used to determine the optical model parameters for the {sup 9}Be+{sup 10}B system at this energy. These parameters are then used in distorted-wave Born approximation (DWBA) calculations to predict the cross sections of the {sup 9}Be({sup 10}B,{sup 9}Be){sup 10}B proton exchange reaction, populating the ground and low-lying states in {sup 10}B. By normalizing the theoretical DWBA proton exchange cross sections to the experimental ones, the asymptotic normalization coefficients (ANC`s), defining the normalization of the tail of the {sup 10}B bound state wave functions in the two-particle channel {sup 9}Be+p, have been found. The ANC for the virtual decay {sup 10}B(g.s.){r_arrow}{sup 9}Be+p will be used in an analysis of the {sup 10}B({sup 7}Be,{sup 8}B){sup 9}Be reaction to extract the ANC`s for {sup 8}B{r_arrow}{sup 7}Be +p. These ANC`s determine the normalization of the {sup 7}Be(p,{gamma}){sup 8}B radiative capture cross section at very low energies, which is crucially important for nuclear astrophysics. {copyright} {ital 1997} {ital The American Physical Society}
