Energy spectra of nuclear inelastic absorption of synchrotron radiation in {alpha}-{sup 57}Fe were measured with 4.4-meV energy resolution in a temperature range 24{endash}400 K. The temperature dependence of the recoil fraction and of the multiphonon contribution was determined. The density of phonon states was derived at each temperature and showed a 4{percent} relative frequency change within the studied temperature range. {copyright} {ital 1996 The American Physical Society.}
