Abstract
We present new measurements of the cross section from to (where c.m. means center-of-mass), which incorporate several improvements over our previously published experiment, also discussed here. Our new measurements lead to based on data from to , where the central value is based on the theory of Descouvemont and Baye. The theoretical error estimate is based on the fit of 12 different theories to our low-energy data. We compare our results to other values extracted from both direct and indirect (Coulomb-dissociation and heavy-ion reaction) measurements, and show that the results of these three types of experiments are not mutually compatible. We recommend a “best” value, , based on the mean of all modern direct measurements below the resonance. We also present factors at which is near the center of the Gamow window: the result of our measurements is , and the recommended value is .
