Chemical shifts in the L3 absorption edge of thulium in TmNix (x = 1,2,3,5 and 8.5) intermetallics were measured and the effective charge on the thulium ion in these compounds was estimated. A linear relation exists between the chemical shifts and the effective charges. It is noted that the chemical shift is a function of only the number of nearest neighbours (coordination number) of thulium in these samples. The probable reasons for the origin of a kink in the L3 absorption curve of thulium in the TmNix system are discussed.
