Mössbauer Effect at High Pressure forFe57in Titanium, Vanadium, and Copper

Abstract

We have measured the effect of pressure to 250 kbar on the isomer shift of Fe 57 in dilute solution in titanium, vanadium, and copper. These results and previously published data on Fe 57 in iron indicate that for the bcc metals of the first transition-metal series, the 4y-electron density scales approximately with bulk density. For more closely packed phases the s-electron density changes less rapidly than the bulk density.
