Description

Two recent calculations by Sen, Rai Dastidar, and Rai Dastidar [Phys. Rev. A 38, 841 (1988); 40, 735 (1989)] discuss intensity-dependent variations of photoelectron angular distributions resulting from (2+1)-multiphoton ionization of H2 via the E, 1Σg+ state and from (3+1)-multiphoton ionization of H2 via the B' 1Σu+ state. In this Comment, we show that most of the intensity-dependent effects presented are a result of an erroneous and unphysical generalization of the angle-independent multiphoton ionization rate to include the angular dependence
