| Abstract: | Based on the Doppler frequency shift effect, the velocity distribution of strontium atomic beam is obtained by measuring the atomic fluorescence spectral induced by a laser beam at a large interaction angle. The comparison and analysis show that the experiment result conforms with the theoretical result fairly well. |
