Superposition states interference pattern

Equation (2.35)]. Equation (15.6b) is formally equivalent to (2.66) with the exception that in the present case the outgoing channel also includes, in addition to the vibrational state, the particular electronic state. It is important to realize that because of the nonadiabatic coupling both excited electronic states and both electronic product channels are populated, even if one transition dipole moment is exactly zero for all nuclear geometries. Furthermore, the superposition of two complex-valued amplitudes in the case that both transition moments are non-zero can lead to interesting interference patterns. 

The picture observed could arise only under following conditions in the slit 1, owing to the interaction of 25-atoms with its metallic walls, coherent mixing of 25 and 2P states occurs, that is the formation of 25-2P superposition. In the second slit, under the influence of similar interaction, the additional coherent mixing of these states takes place, and owing to that, with change of the distance L, oscillations of the 2P-component intensity are observed. It should be emphasized-such an interference pattern can arise only due to considered mechanism-any other reasons cannot cause it. 

If the beams come out in different quantum states because of the interaction with each cavity then, depending on the degree of difference, interference pattern may fade away. Before coming to the quantum state generated by the laser, observe the quantum states associated with the collimated beams, 1 ). They correspond to Hole-l) and Hole-2) states in their linear superposition given in Eqs. (10 and 11). Since the beams cross a laser beam, we have to introduce an operator action equivalent to the one defined in Eq. (17).
