The shift and broadening of the resonance lines in the spectrum of antiprotonic helium atoms pHe + located in fluid and superfluid 4 He have been estimated. The contributions to the shift and broadening from collective degrees of freedom in liquid 4 He have been evaluated using the phenomenological response function. The shift due to collisions ofpHe + with 4 He atoms has been calculated in the quasistatic limit using the experimental pair-correlation function. It has been shown that an implantedpHe + atom establishes a good probe of liquid-helium properties, since this atom practically does not change the target structure.

A new method is presented to calibrate an X-ray energy scale with sub-meV relative accuracy by using the detailed-balance principle of the phonon creation and annihilation. This method is conveniently used to define or verify the energy scale of high-energy-resolution monochromators that are used in inelastic X-ray scattering and nuclear resonant inelastic X-ray scattering instruments at synchrotron radiation facilities. This method does not rely on sample properties and its precision only depends on the statistical data quality. Well calibrated instruments are essential for reliable comparison of data sets obtained at different synchrotron radiation beamlines, of data with theoretical predictions, and of data from other techniques such as neutron or light scattering. The principle of the detailed-balance method is described in this paper and demonstrated experimentally.

“…Singwi and Sjolander [22] adapted the neutron scattering theory to gamma rays and proposed to analyse diffusion in solids or in viscous liquids taking into account broadening of the Mössbauer line. They drew the conclusion that the line broadening in solids depended on the observation angle of diffusion.…”

The method of the Rayleigh scattering of Mössbauer radiation (RSMR) for the study of dynamics of atoms in polystyrene demonstrating advantages of the application of the semiconductor Si-PIN detector (Amptek Inc.) was used for recording scattered radiation. It has been shown that for recording the RSMR spectra the semiconductor detector can be much more suitable than other types of detection because of the increased quality of spectra under the same collimating conditions. The dependence of probability of the Rayleigh elastic scattering fR on the scattering angle was obtained. By means of the RSMR method the scattering was studied within the angle range at the main Bragg maximum of a polystyrene sample which corresponds to the distance d = 4.44 Å approximately equal to the distance between the polymer chains.
