Mass Attenuation

The mass attenuation coefficients of blue sapphire were measured at the different energy of γ-rays using the Compton scattering technique. There are in good agreement of scattered gamma rays energies between theoretical value and experimental value, reflecting the validation of Compton scattering system setup. The results show that, the experimental values of mass attenuation coefficient are in good agreement with the theoretical values. The mass attenuation coefficients increase with the decrease in gamma rays energies. This may be attributed to the higher photon interaction probability of blue sapphire at lower energy. This result is a first report of mass attenuation coefficient of blue sapphire at different gamma rays energies.

In this paper we present the first ever measured Compton profiles of polycrystalline gadolinium and dysprosium using 661.65 keV gamma-rays. The Compton data are compared with renormalized-freeatom (RFA) and free-electron model profiles. In both cases the RFA model (with e− - e− correlation) gives a better agreement with the experiment. The hybridization effects of s-, p-, d-, and f-electrons are discussed, using the first derivatives of the Compton profiles. We also report the cohesive energy of both samples, computed from the RFA calculations. - PACS numbers: 13.60.F, 71.15.Nc, 78.70. -g, 78.70.Ck
