Angular distribution for {sup 7}Be+{sup 7}Li elastic scattering has been measured using a {sup 7}Be radioactive beam at the Nuclear Science Center, New Delhi, at E{sub c.m.}=9.87 and 8.87 MeV. A compact and highly efficient detector system in kinematic coincidence mode and an in-vacuum target transfer system have been developed to minimize contributions from unwanted channels. The angular ranges covered were {theta}{sub c.m.}=42 deg. - 66 deg. and {theta}{sub c.m.}=114 deg. -138 deg. At the backward angles at both energies, the experimental angular distribution shows higher cross sections than the theoretical predictions for the direct elastic channel alone. The experimental data could be fitted with an isospin-dependent complex potential that is analogous to the Lane potential. A coupled-channel calculation with ground-state reorientation could also fit the data.
