Multi-stage Stern–Gerlach Experiment Modeled

Abstract In the classic multi-stage Stern–Gerlach experiment conducted by Frisch and Segrè, Majorana (Landau–Zener) Rabi formulae diverge far from experimental observation while physical mechanism for electron-spin collapse remains unidentified. Here, introducing co-quantum concept provides a plausible predicts in absolute units without fitting (i.e. no parameters adjusted), with p -value less than one per million, which is probability that theory happens to match purely chance. Further, corroborated exactly statistically reproducing wave function, density operator, uncertainty relation electron spin experiments.
