Does quantum mechanics predict the Bremsstrahlung Phenomena? I know it is predicted by classical mechanics through Maxwell's equations, but does QM predict this phenomena and how so?

1$\begingroup$ sorry but this doesn't answer my question as Beth-Heitler approach computed the Cross-section for Bremsstrahlung and their approach did not include the interaction of Z electrons for incident particle traversing the medium plus the screening effect and the solution is not clear for me, i just want to understand how QM is utilized to predict this phenomena. i appreciate your efforts :) $\endgroup$– A OnsiCommented Jun 6, 2015 at 3:19

$\begingroup$ @AOnsi I hate it when people just leave a link of wiki and let it go as if everything is simple as that and as if we did not think looking it up on wiki.... $\endgroup$– medical physicsCommented Aug 23, 2023 at 5:31

$\begingroup$ Could you please, explain how QFT predicted Bremsstrahlung through Feynman Diagram. $\endgroup$– A OnsiCommented Jun 6, 2015 at 3:26

1$\begingroup$ In QED diagrams that can be written consistent with the rules and conservation laws can be transcribed into intergrals with specific format and content. The integration yields the crossection. The reason quantum mechanics is accepted as the underlying level of classical theories is becaus it is successful in describing the experimental values ( crossection and angular distirbutions in this case) also in cases where the classical theory fails ( I do not know if or at what level the classical bremsstrahlung model may be failing). $\endgroup$– anna vCommented Jun 6, 2015 at 10:58
