The iterative regularization procedure has been proposed for recovery of lo
cal density of states from Auger spectra. The algorithm was optimized in mo
del computations. The results obtained from C KLL spectra have been compare
d with C K-alpha X-ray emission spectra and quantum chemical calculations f
or graphite, (CF), and multiwell nanotubes. In polycarbon monofluoride the
interaction energy of holes in the final state of carbon has been estimated
