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