            Abstract : 
Irregularities of the microwave Ramsey patterns in an optically pumped cesium atomic beam frequency standards with a sharp angle incidence detecting laser beam have been diagnosed. They arise from a separated two-peak detected velocity distribution, which is caused by static magnetic fields. Experimentally measured results and theoretical analysis of this phenomenon are presented in this paper.
