We present a beam-split coincidence test of the photon model, previously done with visible light, now performed for the first time with gamma-rays. A similar new test is presented using alpha-rays. In both tests, coincidence rates greatly exceed chance, revealing the flaw of quantum mechanics (QM). A newly formulated threshold model predicted this flaw of QM. We use our threshold model to derive equations for effects thought to require conventional quantization. Conventional quantization denies sub-quantum states that are allowed by the threshold model. Our threshold model embraces Planck's second theory of 1911, where he used h as a maximum. We extended Planck's theory by similarly treating e and m so that all three constants of the electron (h, e, m, for action, charge, mass respectively) are realized as maximum threshold-constants. We then use ratios of those constants, like e/m = Qe/m , for the spreading wave. By quantizing the Q's and thresholding h, e, and m, a matter-wave can spread and load to a threshold upon absorption. Therefore, wave-function collapse is avoided. The quantum disconuity is still present. However our two-for-one effect in our experiments identify a pre-loaded state. Such a pre-loaded state reveals that a loading to a threshold is at play instead of a spooky wave-function collapse. We also identify several false assumptions that made any alternative to QM doomed to fail in experiments designed to reveal the distinction. The difficulty of realizing an experimental distinction between an inside-out threshold and quantization is why quantum mechanics maintained such a strong illusion. ER 5, 21, 2021.
