Conditions for Photon-particle Interactions

摘要

Some aspects of photon-particle interactions are investigated. Although that subject has already been treated in many publications there are still some unsolved problems. To generate a specific process by absorbing photons two conditions have to be met: beside the well known criterion that the energy of the photon has to be equal to the energy needed to the specific process another new criterion is that the length of the photon in time has to be equal to the processing time of the specific process. That means: the processing time and the processing energy are strictly connected to each other.
