摘要：

Coupled-channel calculations for multiphoton ionization probabilities of helium through interaction with intensive short laser pulses are presented. Besides Slater-like orbitals we use regular Coulomb wavepackets in our configurational interaction basis to describe the continuum. Linearly polarized laser pulses of 3.8 fs duration and 2.96 x 10(14) Wcm(-2) peak intensity have been used for frequencies between 0.2-1.2 a.u. The results are compared with other ab initio calculations.
