SUMMARY
The Stern–Gerlach experiment reveals that atoms exiting the oven possess an average energy of 2kT, contrasting with the expected 3kT/2 for gases. This discrepancy is attributed to the effusion process, which alters the speed distribution of the atoms. Specifically, the speed distribution in the beam follows a proportionality of v³exp(-mv²/2kT), diverging from the Maxwell-Boltzmann distribution of v²exp(-mv²/2kT). Understanding this distinction is crucial for interpreting the results of the experiment accurately.
