X-RAY PHOTOELECTRON SPECTROSCOPIC STUDY OF CENTER-DOT-2(PH3P)AUCL-CENTER-DOT-0.1C(6)H(5)CH(3)

We present core level X-ray photoelectron spectra of C-60. 2(Ph3P)AuCl . 0.1C(6)H(5)CH(3) and related compounds. It is shown that the compos ition of surface layer of C-60. 2(Ph3P)AuCl . 0.1C(6)H(5)CH(3) crystal s is very close to that in bulk; the charge transfer between the donor and C-60 is small. Satellite structure near photoelectron peak C1s th at appears due to ''intrinsic'' losses created under photoionization i s observed. The analysis of the satellite structure shows that the los s channel, which is characteristic for all the compounds with Ph3P lig and, is suppressed for C-60. 2(Ph3P)AuCl . 0.1C(6)H(5)CH(3) complex.
