 note = {"In this letter, the spectral asymmetry of the motional Stark spectrum of a neutral beam emission in a toroidal plasma is revealed.  The pi component is more peaked on the more-Doppler-shifted wavelength side about the sigma component, mainly owing to the existence of the angular divergence of the injected beam.  A method using the sigma component to measure the pitch angle in the case of a high magnetic field with an optical system containing two polarizers is also demonstrated.  It is predicted that the pitch angle could be measured with an accuracy of about 2%."},
