Using numerical simulation, injection conditions for the electron in vacuum laser acceleration are studied. The results show that different distribution of injection momentum in the longitudinal and transversal direction will drastically influence the interaction process, and there exists a gap in the frontier area qualified for acceleration. The results for different beam widths show that the gap always exists. This gap corresponds to the valley appearing in the profile of the ejection-energy/injection-angle curve (J. Phys. B, 39 (2006) 1353). Associated with the initial conditions of the interaction system, the characteristic of the ejection-energy/injection-angle curve is also analyzed.
