Look at this gamma downshifting situation in terms of waves. What happens when two waves meet while they travel through the same medium? What effect will the meeting of the waves have upon the appearance of the medium? Will the two waves bounce off each other upon meeting (much like two billiard balls would) or will the two waves pass through each other? These questions involving the meeting of two or more waves along the same medium pertain to the topic of wave interference.
Wave interference is the phenomenon that occurs when two waves meet while traveling along the same medium. The interference of waves causes the medium to take on a shape those results from the net effect of the two individual waves upon the particles of the medium. If the Nuclear active environment is Electromagnetic with the reaction products completely enclosed by the EMF of the soliton, then the various sources of EMF can be seen to interact using standard EMF wave dynamics. If we can assume that the causation of the reaction is a large wave with a power of 10 kilowatts, and the energy of the LENR reaction is 20 MeV, the power of the wave that caused the reaction to occur greatly overwhelms the intensity of the gamma wave that the causation wave produced. When these two waves interfere with each other in a superposition of their wave forms, the energy of the two waves will intermingle on a point by point basis. This type of interference is sometimes called constructive interference. Constructive interference is a type of interference that occurs at any location along the medium where the two interfering waves have a displacement in the same direction. In this case, both waves have an upward displacement; consequently, the medium has an upward displacement that is greater than the displacement of the two interfering pulses. Constructive interference is observed at any location where the two interfering waves are displaced upward. But interference is also observed when both interfering waves are displaced downward. https://www.youtube.com/watch?v=CROUi_f2vGA The guaranty that the gamma and the powerful coherent and entangled XUV soliton will always interfere constructively is based on the certainty that LENR will always occur when the reaction is enclosed by the influence of the soliton. The two waves are always in total contact insuring the wave superposition is total. If the reaction happens the wave form of the energy released by the reaction will be absorbed by the wave that caused it without any exceptions and the reaction wave will always strengthen that wave of causation.
