Abstract
Compton profile studies of TixNi1-x alloys have been made for concentrations x=1·0, 0·74, 0·55 and 0·35. The measurements indicate peaking of the Compton profile at around x=0·5 which corresponds to the composition giving rise to a ‘shape memory’ effect in the alloy. A model involving electron rearrangement between the 3d and 4s states of the individual metals seems to explain qualitatively the observed Compton profile variation with x.
