Abstract
We present calculations of single- and double-ionization rates of helium at 390 nm, accurate to within 10%, obtained from a full-dimensional integrati on of the time-dependent Schrodinger equation. The theoretical results are compared with experimental data at the same wavelength. Excellent agreement is obtained, allowing for likely uncertainties in the experimental determi nation of laser intensity.
