Abstract
We have studied the temperature dependence of the Mössbauer recoil-free fraction and the line shift of in several Sn absorbers between 4 and 375°K. The recoil-free fraction measurements show that the forces on the tin atoms are highly anharmonic. The line-shift measurements are interpreted in terms of a temperature-dependent electron density at the tin nucleus, which is shown to support previous suggestions of a very narrow band near the Fermi level.
