East Carolina University


Professor Gregory Lapicki has completed his PhD at the age of 30 from New York University and continued with postdoctoral studies for two years in the Radiation and Solid Laboratory at NYU. In 1991-92, worked at Centro Atómico, Bariloche, Argentina on the Fulbright Award. In 2013-2017, served on the International Advisory Committee for Particle Induced X-ray (PIXE) Conferences; presented opening invited talks at five of these conferences. In 2017, elected to the International Honorary Committee for PIXE. Multiple times presented invited talks at the International Symposium on Ion-Atom Collisions and the Conference on Applications of Accelerators in Research and Industry, for which in 2017 served as atomic and molecular physics topic editor. Published almost 200 refereed papers in journals such Physical Review A, Nuclear and Instruments and Methods in Research B, Journal of Physics B, Journal of Physics and Chemistry Data, X-Ray Spectrometry, Radiation Physics and Chemistry, with a link to one of the most recent publications in Atomic and Nuclear Data Tables.

Research Interest

Theoretical atomic physics. Inner-shell ionization and energy loss of charged particles in matter. Development and improvement of the ECPSSR theory of K-, L-, and M-shell ionization that is widely used for comparison with x-ray and Auger-electron production cross sections; in particular in PIXE analysis.
