I loved the paper. I struggled with the last question until I had a brain wave and came up with that the resultant momentum for a head on collision would be 0 so all of the energy of the particles would have been converted to mass-energy whereas with a non head on collision the resultant momentum would be > 0 so the resulting particles would have a non 0 kinetic energy and thus not all energy from collision would have been converted to mass-energy
