Cross section data are compiled from the literature for electron collisions with nitrogen trifluoride (NF$_3$) molecules. Cross sections are collected and reviewed for total scattering, elastic scattering, momentum transfer, excitations of…

Dark energy and dark matter are only indirectly measured via their gravitational effects. It is possible that there is an exchange of energy within the dark sector, and this offers an interesting alternative approach to the coincidence…
