heal.abstract	The paper reports results from the application of the many-electron, many-photon theory on the system 'H- 1s(2) S-1 state plus two fields of weak strengths, F-1 and F-2'. The two fields have commensurate frequencies (a), 2(0) and (omega, 3 omega), with omega ranging from 0.011 au to 0.028 au, field strengths from 5 x 10(-5) au to 1.7 x 10(-3) au and a phase difference phi. It is possible to determine the regime where the dichromatic field is weak and to define and compute a corresponding 'interference generalized cross-section'. This cross-section is an intrinsic property of each state as a function of the pair (omega, m omega), m = 2, 3, . . . . Its knowledge is directly relevant to deciding on the degree of effectiveness of coherent quantum control. The calculations show that, with respect to 0, His more receptive to control if frequencies are low. The computed effects are large enough so as to be measurable.	en
