In a previous section we have mentioned that the reaction of the electrons’ ensemble bound in an atomic MS (electrons which make-up its peripheral medium), at the incidence of an external energy flux is the same for any type of MS: the incident flux shall be opposed to the reaction flux, until one of the fluxes (either the incident or the reaction one) would have been depleted its resources. If the energy provided by an external EF is higher than the EF re-circulated between the two EP, the couple shall split (the expulsion of the EP from the system shall be produced). If this energy is less, EP which receive the flux shall be temporarily transferred on a EO with a higher energy (absorption-storage stage of the incident EF), until the exhaustion of the EF, and then, the reverse process of resending the energy surplus (temporarily stored EF) to the outside (reflection) shall come next, also as a photon generated by the emission transition of the driven electron.
At this moment, the reader is invited to be very attentive because we shall talk about a process - that is the reflection of a photon on an atom (or on any other atom set which makes-up the surface of an object) - from a different perspective than the one specific to the current physics textbooks. Based on the above-mentioned facts, it may result that at the incidence of a photon on an atom (more exactly, on an electron placed on a peripheral orbital), which means that the photon is an incident EF, the first stage of absorption/storage of this EF shall exist, storage into the energy of the driven electron which passes on an excited orbital.
Attention! The photon’s energy was entirely transferred to the electron placed on the excited orbital, otherwise speaking, starting with this moment, the incident photon does no longer exist, but its energy does, even if this energy is under another form (without the component T). The process which is equivalent with the transformation of the coherent incident flux into a stochastic or periodical flux, without the component T of the initial photon126, took place. After the storage interval (which is shorter in case of the instable excited orbital, or non-determined in terms of time in case of a metastable orbital), the emission transition takes place, that is a process in which the couple excited electron_proton partner shall generate to the outside a photon with the energy equal with the temporarily stored one. But, once again, pay attention, the generated photon (equivalent with the reflected EF) is not the same with the incident photon but it is generated into the electronic medium of the atom which was previously driven by the former incident photon.
This fact explains in a natural and coherent manner why a photonic flux reflected by the surface of a body carries with oneself some data about the chemical composition of the body; this is natural, because the reflected photons are generated by the atoms of that particular body, while the incident photons are produced into the source of the incident photonic flux.
126 In case of the excited electron, the flux stored without the component T is also a coherent but rotational flux (periodical), that is the electron’s orbital motion deployed on the excited orbital.
