Coulomb dissociation of $^{8}\mathrm{B}$ into the $^{7}\mathit{p}$ low energy continuum is studied theoretically in first- and second-order perturbation theories and in the sudden approximation. The summation over all intermediate continuum states in the second-order amplitude is achieved by closure, using an expansion which is valid for low excitation energies. In view of the importance of the $^{7}\mathrm{Be}$(p,\ensuremath{\gamma}${)}^{8}$B reaction for the $^{8}\mathrm{B}$ solar neutrino problem we investigate especially the optimal conditions for possible experiments. Double as well as triple differential cross sections are calculated for 5 MeV/A, 46.5 MeV/A and 200 MeV/A beam energy as a function of the $^{8}\mathrm{B}^{\mathrm{*}}$ scattering angle, the $^{7}\mathit{p}$ relative energy, and momentum.
