Abstract

Analysis of ⁸B dissociation with the Asymptotic Normalization Coefficient (ANC) method is proposed to determine the astrophysical factor S₁₇(0) accurately. An important advantage of the analysis is that uncertainties of the extracted S₁₇(O) coming from the use of the ANC method can quantitatively be evaluated, in contrast to previous analyses using the Virtual Photon Theory (VPT). Calculation of measured spectra in dissociation experiments is done by means of the method of Continuum-Discretized Coupled-Channels (CDCC). From the analysis of ⁵⁸Ni(⁸B,⁷Be+p ⁵⁸Ni at 25.8 MeV, S₁₇(O) = 22.3 ± 0.64(theo) ± 2.23(expt) (eVb) is obtained; the ANC method turned out to work in this case within 1% of error.
