Direct observation of the transversal Doppler-shift
Abstract
An experiment is reported in which the second order Doppler-shift has been determined by the observation of the Hα-line emitted by linearly moving hydrogen atoms of velocities 2.53×108 cm/s-9.28×108 cm/s. In contrast to previous experiments the direct transversal observation has been used for the first time. The coefficient of the second order term in the relativistic approximation is found to be 0.52±0.03 which compares good with the theoretical value of 1/2.
