Abstract: | The cross section for the reaction has been measured at θlab = 135° over the proton energy range 93 ≦ Ep ≦ 418 keV. The results are in good agreement with the less precise but much earlier measurements of Schardt, Fowler and Lauritsen (1952). An analysis of the present data in terms of a two-level calculation including the 338 keV (1?) and 1028 keV (1?) resonances determines a zero-energy intercept for the astrophysical S-factor of S(0) = 78 ± 6 MeV · b. |
