Charge Transfer Between d-p States in Ti02 By Employing Compton Scattering Techniques

The complon profiles for Ti02 have been measured using a 5Ci Am-241 compton spectrometer .A pellet of the oxide was prepared from a polycrystalline powder having a thickness of 1.54 mm ,about 100000 counts have been accumulated at the compton peak .Theoretical compton profiles have been calculated lor different ionic arrangements using free atom compton profile for the core electrons.The theoretical and experimental results ahrce well for ( T i ) , 4 ( 0 2 ) 2 arrangement which support complete transfer of valence electrons from metal to oxygen ions, i.e., full ionic bonding in this oxide in agreement with available photoemission and other studies .
