Abstract We investigate the effects of higher order multipole transitions, in particular electric quadrupole (E2) and E1--E2 interference, on the Coulomb dissociation of 19C within the framework of the first order eikonal approximation. The sensitivity of the total Coulomb breakup cross section and the longitudinal momentum distribution of the core fragment to these effects are checked. The breakup occurs predominately through the dipole transition and the contribution of E2 transition to the total cross section is found to be within the range from 1 to 3% of that of E1. It is further observed that the E1--E2 interference term contributes nothing to the integrated cross section. On the other hand, the longitudinal momentum distribution is observed to be insensitive to the E2 transition while the E1--E2 interference introduces a small asymmetry in its shape.
