Abstract

The Doppler shape of the NaI 589,0 nm line in the case of bombardment of the NaCI crystal normally to the surface by the K+ ions with the energy of 7 keV for the pri­mary ions current of 40 mkA was measured. The measurements were carried out for fixed azimuthal and different polar angles of observation of radiation α=850, 450 and 150. The intervals of the characteristic velocities projections on the direction of the radiation observation were determined to be (-1, 1÷1)·106 cm/c, (-0,6÷1,4)·106 cm/c and ( 0,2÷2)·106 cm/c for α=850, 450 and 150, respectively. From the obtained results the angular distribution of the excited Na atoms are shown to be sub­stantially stretched along the normal to the surface.
