Interaction on surface and nanocapillarity induced by highly charged ions in low and medium energy regime
Dr. Yuyu WANG - Institute of Modern Physics (IMP), CAS, Lanzhou, CHINE Mardi 28 août à 10h30 - Salle de réunion du CIMAP GANIL In comparison with swift heavy ions (SHI), highly charged ions (HCI) carry several tens of keV potential energy. Most of the potential energy is deposited within a few nm of first few atomic layers of the surface on the fs time scale, effective energy deposition rates can exceed about 1014W/cm2. How the potential energy is deposited into the surface and the respond (...)
Double ionisation de l’hélium par impact électronique : limitations des descriptions théoriques
Ugo ANCARANI Laboratoire Structure et Réactivité des Systèmes Moléculaires Complexe - Université de Lorraine, Metz 24 avril 2013 It has been stated that the three‐body Coulomb problem has been solved numerically, the proof being given through calculations of the single ionization ((e,2e) process) of hydrogen by electron impact [1]. Several numerical recipes like the Convergent‐Close‐Coupling [2], the Exterior‐Complex‐Scaling [3], the J‐matrrix [4], among others, managed with great success to (...)
Sulfur and Carbon Cycles in the Icy Moons of Jupiter
Giovanni STRAZZULLA - INAF-Osservatorio Astrofisico, Via s. Sofia 78, 95123 Catania, Italy (gianni@oact.inaf.it) Mercredi 29 mai à 10h30 à la maison d’Hôtes du GANIL The surfaces of the icy moons of Jupiter are continuously modified by ion implantation of energetic ions and electrons from the magnetosphere. The study of the induced effects is based on based on laboratory simulations aimed e.g. at investigating the induced non-thermal chemical reactions that lead to the formation of a large (...)
Low Energy Electron Interaction with DNA
Professeur S. K. V. KUMAR PAM Laboratory - Tata Institute of Fundamental Research, Mumbai, Inde Jeudi 30 mai 2013 à 14h30 - Salle de réunion du CIMAP SUD Low energy electrons (LEEs) are produced in copious amounts by the primary radiation used in radiation therapy. Sanche and co-workers in 2000 revealed that LEEs can also cause measurable damages to DNA and the damage is caused at specific electron energies. Experiments have been performed at TIFR, Mumbai to see if the differences in (...)
