The target was mounted on the axis of a A041400100030 stepping motor, which moved the target by a 180 degreesA041400100031 rotation between the proton-beam irradiation position A041400100032 and the 8-B-decay counting position, in a repeating A041400100033 cycle. A041400100034 DETECTOR (SIBAR) A041400100035 METHOD (SITA,BCINT) A041400100036 ADD-RES Spectrum of the beta delayed alpha-particle A041400100037 COMMENT -Abstract: the absolute cross section for the A041400100038 radiative capture reaction 7-Be(p,gamma)8-B at the A041400100039 center-of-mass energies E = 0.32 to 2.61 MeV has been A041400100040 measured using a 7-Be target deposited on a Cu backing A041400100041 and observing the beta-delayed alpha-particles from A041400100042 8-B. The backing causes a loss of less than 1% of the A041400100043 8-B residual nuclides. The resulting astrophysical A041400100044 S(E) factor at zero energy, S(0) = 18.4+/-1.6 eV*B, is A041400100045 consistent only with a restricted data set from A041400100046 previous work.
