معرفی
Dr. Gregory Lapicki is a Professor in the Department of Physics at East Carolina University, with his office located in Howell Hall E308. He can be contacted via telephone at (252) 328-6894 or email at lapickig@ecu.edu.
He earned his PhD in Physics from New York University in 1975. His academic career spans over five decades with a focus on theoretical atomic physics.
Dr. Lapicki's research centers on inner-shell ionization and energy loss of charged particles in matter, with significant contributions to PIXE (Particle-Induced X-ray Emission) analysis methodology. He developed the ECUSAR theory for L-shell X-ray production cross sections, which shows excellent agreement with experimental data. His work has accumulated approximately 3650 citations, reflecting substantial impact in the field of atomic collision physics.
Analysis of his 15 most recent publications (2012-2023) reveals persistent refinement of theoretical models for K-, L-, and M-shell ionization cross sections. Key trends include universal empirical fits for proton-induced X-ray production, proton/helium ion comparisons, and applications in elemental analysis. His research bridges fundamental atomic collision theory with practical PIXE applications in material science.
His notable recognition includes serving on the International Honorary Committee for PIXE conferences, highlighting his leadership in the field.
Dr. Lapicki teaches core physics courses including General Physics, University Physics, Mathematical Methods, Mechanics, and Quantum Physics at undergraduate and graduate levels. While no specific grants or student advising are mentioned in available records, his extensive publication record demonstrates sustained research activity.
Although the ECU Department of Physics maintains specialized laboratories like the Radiation Instrumentation Lab, Dr. Lapicki's theoretical work operates independently of experimental facilities, focusing on computational modeling and cross section compilation.
