To explore the nature of the coupling effects on p+Be-10 and p+Be-11 elastic scattering at incident energies of 39.1A and at 38.4A MeV, respectively, coupled reaction channels (CRC) calculations were performed for the Be-10(p,d)Be-9 and Be-11(p,d)Be-10(*) pickup to the ground state of Be-9 and the 5.960 MeV 1(-) and 6.263 MeV 2(-) doublet of excited states in Be-10 at the corresponding incident energies. We show that within the CRC framework, the coupling effect on the elastic scattering is significant in both cases and produces effective absorption in the entrance channel. This suggests that the use of a fitted p+Be-10 optical model potential may lead to too much absorption in the core plus proton interaction in extended coupled discretized continuum channels type of calculations for the p+Be-11 system and that coupling to the Be-11(p,d)Be-10(*) pickup should be explicitly included in such studies.
