3-(p-Toluidino)-5-phenyl-1-p-tolyl-1H-pyrrol-2(5H)-one as an organic liquid scintillator used for gamma spectroscopy

In this article, the scintillation properties of 3-(p-toluidino)-5-phenyl-1-p-tolyl-1H-pyrrol-2(5H)-one as a Lactam is studied. m-xylene, cyclohexan, and ethanol are used as solutions, whilst, Anteracene and Naphthalene are used as secondary solvents. The influence of solvent on the scintillation efficiency is studied. The results show that the proposed material can be used as an organic scintillator but its efficiency for gamma spectroscopy is relatively low (～5% of NE213 of similar size).     

Proton-deuteron radiative capture cross-sections at intermediate energies

Differential cross-sections of the reaction p(d, ³He)γ have been measured at deuteron laboratory energies of 110, 133 and 180 MeV. The data were obtained with a coincidence setup measuring both the outgoing ³He and the photon. The data are compared with modern calculations including all possible meson-exchange currents and two- and three-nucleon forces in the potential. The data clearly show a preference for one of the models, although the shape of the angular distribution cannot be reproduced by any of the presented models.     

Calculation of A x for the Proton–Deuteron Breakup Reaction at 135 MeV

Observables in proton–deuteron scattering are sensitive probes of the nucleon-nucleon interaction and three-nucleon force effects (3NF). Several facilities in the world, including Kernfysisch Versneller Instituut (KVI), allow a detailed study a few-nucleon interaction below the pion-production threshold exploiting polarized proton and deuteron beams. In this contribution we explored 3NF effects in the break-up scattering process by performing a measurement of differential cross section and the analyzing power, especially the x component of the analyzing power, using a 135 MeV polarized-proton beam impinging on a liquid-deuteron target. The proton–deuteron breakup reaction leads to a final state with three free particles and a rich phase space that allows us to study observables for continuous set of kinematical configurations of the outgoing nucleons. The results are interpreted with the help of state-of-the-art Faddeev calculations.
