摘要：
We investigate numerically the solution of Dirac equation and analytically the Klein-Gordon equation and discuss the relativistic motion of an electron wave packet in the presence of an intense static electric field. In contrast to the predictions of the (non-relativistic) Schrodinger theory, the spreading rate in the field's polarization direction as well as in the transverse directions is reduced.
