Description:
Experimental and theoretical demonstration of the necessity to take into account the effects of diffraction at a spectrometer's entrance slit in adjusting the spectrometer for observation of fast-beam spectral lines under conditions of minimum linewidth. An approximate expression is obtained for the optimum entrance slit width to be used in order to avoid the pronounced broadening of the spectral lines that occurs for very narrow entrance slits.
