We study the energy level shifts of an accelerated multilevel atom in dipole coupling to the derivative of a quantum massless scalar field and separately calculate the contributions of vacuum fluctuations and radiation reaction to the shifts.It is found that,in contrast to the case of a monopole-like interaction,both the vacuum fluctuations and radiation reaction contributions are changed by acceleration,and they all contain non-thermal correction terms.Our results suggest that the effect of acceleration on the energy shifts is dependent on the type of the interaction between the atom and the quantum field.
