Using the (r, t') method the time-dependent Schrôdinger équation for two electronic potential surfaces which are coupled via a time-dependent (not necessatily time-periodic) field is transformed ffom the length to momentum, reduced momentum and accélération gauge représentations. Combining the (t, tr) method and complex scaling enables the calculation of partial widths by the asymptotic analysis of the tail of the résonance wavefunction obtained in the length gauge after being transformed to the accélération gauge such that a ftee particle is obtained as R (the reaction coordinate) oo regardless of the shape of the laser puise. As an illustrative numerical example the partial widths of Hj in high periodic fields are calculated.
