Resumen
Elastic scattering and transfer cross sections for the 7Be + 9Be system have been measured at Elab =
23.1 MeV using the 7Be radioactive secondary beam produced at Radioactive Ion Beams in Brazil facility
at the University of S??o Paulo. The elastic scattering has been measured by detecting the 7Be scattered at
forward angles in the laboratory system. The transfer reaction 9Be(7Be, 9Be)7Be was identified by detecting
the 9Be scattered at the same laboratory angles. The elastic angular distribution has been analyzed by optical
model calculations using a Woods-Saxon form factor whose parameters have been varied to best reproduce the
experimental data at forward angles. Coupled reaction channels calculations (CRC) have been performed to
describe the transfer, considering the coupling to the transfer channel and including contributions to the ground
state and to the first excited state of 7Be(1/2???; 429 keV) in the final state. The spectroscopic amplitudes used in
the CRC calculation have been derived from shell-model calculations. Similar CRC calculations were applied to
existing 9Be(p, t )7Be data to check the consistency of our results results for the (7Be, 9Be) transfer reaction. Funda????o de Amparo ?? Pesquisa do Estado de S??o Paulo (FAPESP) FAPESP: 13/22100-7; 16/21434-7
