Among the topics are electron capture processes in ion-atom collisions at intermediate projectile energies, recent advances in the theory and modeling of multiple processes in heavy-particle collisions, distorted wave methodologies for energetic ion-atom collisions, and studying inelastic processes in ion-water collisions using classical trajectory Monte Carlo and semiclassical methods.
The most notable device is the electron capture detector, an instrument that has made it possible to detect atmospheric chlorofluorocarbons, and ultimately assisted in knowledge of the ozone layer's depletion in our stratosphere.
I then chose three species, 3H (a pure beta emitter with no gammas), 18F and 22Na (both of which decay by both electron capture and positron emission) and was somewhat surprised to see them as having no betas or, in the case of the latter two, as undergoing electron capture with no mention of positron decay.
When explosives vapors are introduced into the electron capture detector (ECD), the detector's standing current changes, and an electronic signal goes off, indicating the presence of an explosive or another electronegative compound.
