The elastic breakup of the deuteron has been measured in a kinematical condition of [Formula Presented] at [Formula Presented] and 270 MeV on seven targets ranging from [Formula Presented] to 82. A double-peaked structure with its minimum at [Formula Presented] is observed for all the measured triple-differential cross sections, which indicates a large contribution from Coulomb breakup. While a symmetric shape is expected for an [Formula Presented] transition, the observed proton-energy distribution is asymmetric, showing considerable dependence on both the target and the incident energy. These data and previous data at 56 MeV have been analyzed using the post-form of the distorted-wave Born approximation (DWBA) theory. Although the calculations account reasonably well for the asymmetric shape, by including the nuclear potential, they consistently overestimate the magnitudes of the cross sections over the whole measured region. Limitations of the post-form DWBA are discussed.
