SEMI-CLASSICAL THEORY ON BIOPHOTON EMISSION
生物光子发射的半经典理论

Biophoton emission (PE) method is a non-invasive way revealing biophysical interactions in living tissues. Since its mechanism is not very clear, its acceptanee is limited. Gu has presented the quantum theory on biophoton emission according to the Dicke model. However, the Dicke model does not even apply to a DNA. In this paper, we studied PE by using the identical particle model, the interaction of identical particles by quantum chemistry, as well as the transition of the system interacting with radiation by semiclassical approach. It was shown that the identical particles could form coherent states in which the photon emission probability of the superradiant state is a liner function of N2 and N2(N is the particle number). The research on the cell division cycle showed that the superradiant states correspond to the late S phase.This is why PE can be used to distinguish human tumor tissues from nounal ones. We also studied induced PE.
