The Global Network for the Atomic and Molecular Physics of Plasmas (GNAMPP) is a consortium of research groups working in the area of fundamental atomic and molecular physics relevant to plasma processes. Its focus is on promoting collaboration and communication between experimentalists and theoreticians to improve the quality and completeness of data used in modelling and interpreting fusion plasmas.
GNAMPP provides a forum for the evaluation, validation and dissemination of data, the benchmarking of relevant modelling codes and the formulation of research guidelines and priorities.
The Scientific Advisory Committee is:
Laboratoire de Chimie Physique – Matière et Rayonnement (LCPMR) at Sorbonne Université
Our expertise is the modeling of electronic processes occurring in the course of collisions between low-charge ions and atoms or molecules. We are particularly interested in the so-called intermediate energy domain where the inelastic processes (capture, excitation and ionisation) are strongly coupled. We base our calculations on a semi-classical non-perturbative approach which requires to solve the time dependent Schrödinger equation. Our team have developed several home-made codes which take into account up to four active electrons. These codes allow us to compute integral and differential cross sections, see for example the figure below in which the double electron capture cross sections are plotted as function of impact energy for the C4+-He collision system.
