Absolute cross sections for the ${\mathrm{Be}}^{7}(p,\ensuremath{\gamma}){\mathrm{B}}^{8}$ reaction have been measured at 8 proton energies between 483 and 1932 keV. These measurements have been used to obtain a zero-energy intercept of the cross-section factor $S(E)$ for this reaction, ${S}_{0}=0.043\ifmmode\pm\else\textpm\fi{}0.004$ keV barn. A resonance was observed in the ${\mathrm{Be}}^{7}(p,\ensuremath{\gamma}){\mathrm{B}}^{8}$ reaction, corresponding to the first excited state of ${\mathrm{B}}^{8}$, and a radiative width of 0.050\ifmmode\pm\else\textpm\fi{}0.025 eV was obtained for this state.
