We study the excitation to Rydberg states in the interaction of the hydrogen and helium atom with a short strong laser pulse, as it has been analyzed before for monochromatic cw lasers. Utilizing solutions of the time-dependent Schrödinger equation we have analyzed if the parity of the populated angular momentum states agrees with the selection rules for multiphoton resonant absorption. We have further investigated how the results and conclusions depend on the parameters of the laser pulse, such as intensity and pulse length. Different mechanisms to explain the distributions in the populations of the angular momentum states are tested by our simulations.
