In this paper, we derive an expression of energy gain in a laser electron accelerator by using a general covariant coordinate transformation. It is pointed out that even when the external gravitational field, is absent, the electrons will still be additionally accelerated by the influence of background medium. In the vacunm case, the obtained results agree with those obtained by the Lorentz transformation.

Photoionizing decay of the autoionizing state is taken into account in the model of strong laser field induced autoionization. Photoemiss ion spectra are recalculated and significant power broadening of these spectra is found, which is in contrast with previous predictions using. simpler model.
