The adequacy of the approximation method used by McMillan and Opechowski in their theoretical study of the temperature dependence of the paramagnetic resonance line shape function is very difficult to ascertain for the case of a typical paramagnetic crystal. For this reason the approximation method has been investigated for the very simple case of the one-dimensional Ising model. Exact expressions for the line shape function of the model are compared with expressions obtained by the approximation method mentioned above. The agreement between the two expressions is found to be very good in general, and extremely good at very low temperatures.

AbstractQuasielastic Rayleigh scattering of 14.4 keV Mössbauer γ-radiation has been measured on 1,3-butanediol, yielding the width Γ of the central line (assumed to be Lorentzian) and its relative intensity, for momentum transfers corresponding to molecular dimensions (k = 0.9... 2.5 Å-1) at 243 K. Γ (k) rises fast and then saturates. An effective correlation time τ and jump width is derived characterizing the diffusional motion of individual molecules considered as entities. Fast motions (vibrations, librations) are taken into account explicitly. The correlation time τ compares well with results from other experiments. The temperature dependence was followed from 208 up to 263 K.

From the invention of the Optical Tweezer (OT) in 1986, these devices have been considered as high-level tools for research in the areas such as biology and microbiology. A theoretical study obtaining equations for gradient and scattering forces that exert an OT when the illumination beam is a doughnut-shaped mode TEM∗01 linearly polarized is realized. This work focuses on the behavior of radiation forces on a dielectric sphere in the Rayleigh regime. In order to facilitate the phenomenological analysis of the behavior of the radiation forces a graphical user interface is created.
