摘要：

In the first Born approximation, the symmetrical double-electron-capture collision between an cr particle and a helium atom in the presence of an intense laser field is studied. The capture cross section is promoted considerably and is an increasing function of the ratio of the laser amplitude to frequency. With increasing impact energy, the dressing modification becomes notable.
