摘要：

We have determined the ratio of the s and d Auger-decay amplitudes and their phase difference for the resonant Auger transition 2p(3/2)(-1)4s --> 3s(-1)3p(-1)4s(P-2) from the measurement of the angular correlation between the resonant Auger emission and the subsequent second-step Auger emission, as well as the angular distribution measurements for these two electron:emissions. The analysis of the experimental data is based on the nonrelativistic LSJ coupling approximation.
