In this study, we aimed to determine coherent to Compton scattering differential cross section ratios of some inorganic materials (BaSO4, CaF2, Mg2SiO4, MgSO4, and ZnSO4(7H2O)) for several scattering angles (95°, 105°, 115°, 125°, and 135°). Coherent to Compton scattering differential cross section ratios were investigated experimentally by using an HPGe detector, which has a resolution of 199.6 eV at the 5.9 keV. The samples were excited with 59.54 keV gamma rays emitted from Am241 point source. The intensity ratios were corrected due to the photopeak efficiency of the gamma detector and absorption of photons in the target and air. It is observed that coherent to Compton scattering differential cross section ratios decrease with increasing scattering angle.

The coherent to Compton differential cross section ratios were calculated for elements in the range 20 ≤ Z ≤ 32 under an external magnetic field. The elements were irradiated by 59.54 keV gamma rays from an 241Am radioactive source. A Si(Li) detector was used to detect the scattered photons. It was observed that the coherent to Compton differential cross section ratios of the samples increase with the magnetic field (B = 0, 0.4, and 0.8 T). The theoretical results were obtained with two different methods and compared with the experimental results at 0 T.

Deuteron breakup reactions are basic laboratories for testing nuclear force models. Recent improvements in the data analysis allow for direct identification of neutrons in the BINA detection setup. This opens up the opportunity to study new aspects of few-nucleon system dynamics like charge dependence of nuclear force or Coulomb interaction. In this paper we determine regions along the kinematical curves where differential cross section of deuteron-proton breakup reactions can be measured by the proton-neutron and proton-proton coincidences simultaneously. %In this paper we determine regions along the kinematical curves where differential cross section of $^1$H$(d,pp)n$ and $^1$H$(d,pn)p$ breakup reactions overlap. This is particularly useful for validation of the neutron detection technique.
