Abstract
The shape of the Ne KL2Ls (1D2) diagram Auger line has been investigated in the 5.5 MeV/u N2+- and Ne3+-Ne collisions. An asymmetric line shape has been found showing up a tail on the high energy side of the line, while the shape of the line due to the 1s2s2p(4P-1s2(1S) transition from the Li-like metastable initial state measured in the 5.5 MeV/u Ar16+-Ne collision was symmetrical. The line shape calculated according to a post collision effect due to the slowly receding ejected electrons shows a very good agreement with the measured line shapes.
