A kinematically complete measurement was made of the Coulomb dissociation of {sup 8}B nuclei on a Pb target at 83MeV/nucleon. The cross section was measured at low relative energies in order to infer the astrophysical S factor for the {sup 7}Be( p,{gamma}){sup 8}B reaction. A first-order perturbation theory analysis including E1 , E2 , and M1 transitions was employed to extract the E1 strength relevant to neutrino-producing reactions in the solar interior. By fitting the measured cross section from E{sub rel}=130 to 400keV, we find S{sub 17}(0)=17.8{sup +1.4}{sub -1.2} eV b .
