Riassunto Si effettua un confronto fra le forme di riga degli spettri AugerXVV di una lega di Fe−Ni sperimentali e quelle determinate teoricamente, usando teorie recenti che tengono in conto la correlazione coulombiana fra le due buche Auger. Per il sistema in esame la teoria dà risultati in stretto accordo con i dati sperimentali, almeno per quanto riguarda gli spettri a bassa energia. Il confronto con i dati sperimentali ad alta energia è in qualche modo complicato dalla struttura asimmetrica dei picchi sperimentali, dovuta ad effetti satelliti.
Notes:
Summary A comparison is performed between theoretical and experimental shapes of theXVV (X=M 2,3 andL 3) Auger spectra of ferromagnetic Fe x −Ni1−x alloys forx=0.48 and 0.27 in order to check if recent theories, which take into account the Coulomb correlation between the two final Auger holes, would be able to reproduce shape and position of the experimental peaks in an accurate way. For the case under investigation, it seems that, at least for the low-energy (M 2,3 VV) spectra and notwithstanding the usual neglecting of matrix element effects, the theory gives results in close agreement with the experimental data. The comparison with the high-energyL 3 VV spectra is somewhat hampered by an asymmetric broadening of the experimental data on the low kinetic-energy side due to satellite structures, but still gives good agreement on the high kinetic-energy side.
