Abstract
We show that the autoionization line shape can be modified by the choice of two laser intensities and the relative phase. Under well specified conditions, proper choice of the phase can lead to selective cancellation of the transition to the discrete or the continuum part of the state. Application of the idea to a multichannel problem in the rare gases also provides significant effects.Keywords
