摘要：

Alloying effects on the K-shell fluorescence yield omega(K) of nickel in Ni-Si binary alloy system have been studied by energy dispersive X-ray fluorescence. It is found that omega(K) increases from pure Ni to Ni2Si and then decreases from Ni2Si to NiSi. These results are discussed in terms of d-occupation number on the Ni site and it is concluded that electronic configuration as a result of p-d hybridization explain qualitatively the observed variation of omega(K) in Ni-Si alloys.
