Erwin Gabathuler was born in Maghera, County Londonderry, Northern Ireland on 16 Novembera son of the manager of the Swiss embroidery attended Rainey Endowed School, Magherafelt, and then Queen's University he studied physics, and was awarded BSc inand MSc in for a thesis on "Electron Collision Cross-sections of Atmospheric Gases".

Cross sections can be computed for atomic collisions but also are used in the subatomic realm. For example, in nuclear physics a "gas" of low-energy neutrons collides with nuclei in a reactor or other nuclear device, with a cross section that is energy-dependent and hence also with well-defined mean free path between collisions.

Abstract Momentum-transfer and inelastic-collision cross sections for electrons in O 2, CO, and CO 2 are calculated from measured values of the electron drift velocity, characteristic energy, attachment coefficient, and ionization coefficient.

The experimental data for O 2 are most consistent with vibrational excitation cross sections consisting of a series of resonances located at the.
