DIFFRACTION WITH WELL-DEFINED PHOTON TRAJECTORIES - A FOUNDATIONAL ANALYSIS

We assume: (i) Photon's are emitted by harmonically oscillating source s. (ii) They have definite trajectories. (iii) They have a probability of being scattered at a slit. (iv) Detectors, like sources, are perio dic. (v) Photons have positive and negative states which locally inter fere, i.e., annihilate each other, when being absorbed. In this framew ork we are able to derive standard diffraction and interference result s. We thereby eliminate in this approach wave-particle duality for pho tons, and give nonparadoxical answers to standard questions about inte rference. For example, in the two-slit experiment each photon goes thr ough only one slit.
