Abstract
We report a high-resolution coincident experiment between
the Ar 2p1/2 and 2p3/2 photoelectrons and subsequently
emitted L23-M23M23 Auger electrons, where the 2p
photoelectrons were ionized far above the threshold. We
demonstrate the applicability of the coincidence method
when separating the different ionization and decay
channels even in the case of strongly overlapping peaks.
The measurement was carried out with a new
high-energy-resolution electrostatic analyzer that is
capable of recording the single and coincidence spectra
at large range of emission angles simultaneously. An
anomalous value was found for the 2P3/2-(3P012/1D2)
intensity ratio in the 2p3/2 coincidence spectrum, while
all the other relative intensities are in good agreement
with the previously published data. The possible reasons
for the difference are discussed.
