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
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.
