Abstract
The radial velocity distribution and Doppler width distribution of Gd metal atomic vapor heated by the liner electronic gun is measured by the dye double laser induced fllorescence. With demarcating the velocity by isotope displacemen characteristic, the measuring device is simplifyed. The radial velocity and Doppler width distribution of belted atomic vapor are given. The radial velocity approximately linearly decreases with |β| angle increasing. The Doppler width approximately linearly increases with |β| angle increasing.
