A deconvolution technique to eliminate the azimuthal contribution from two-dimensional (2D) images of three-dimensional momentum trajectories is presented. The technique, which in some respects is superior to Abel and similar numerical inversion methods, exploits numerical simulation to generate a 2D polar representation of the dynamics where the radius from the center of the image is proportional to the magnitude of the momentum and the angle is the ejection angle relative to the polarization axis of the laser. A sample deconvolution for the three-body Coulomb explosion of NO2 is shown.
The average energy of the electrons produced in anthracene scintillators by 7-rays in the energy range from 0.28 to 2.76 Mev is determined experimentally. The values obtained are in good agreement with theory. Above 1 Mev 7-ray energy, crystal size is shown to be of importance due to leakage of high energy electrons from the crystal surfaces.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
