Breakup of 7Li near the alpha -t threshold and a possible probe of radiative-capture processes.

Breakup of 63-MeV and 42-MeV {sup 7}Li near the {alpha}-{ital t} threshold is examined from the astrophysical point of view. A new approach is made to extract indirectly astrophysical {ital S} factors. The {ital S} factors are compared with those deduced from radiative-capture measurements. It is shown that the energy dependence favors the recent capture data of Schroeder {ital et} {ital al}.
