Alexandre Obertelli

from Wikipedia, the free encyclopedia

Alexandre Obertelli (born April 10, 1978 in Paris ) is a French experimental nuclear physicist.

Life

From 1999 Obertelli studied physics at the University of Paris XI with a master’s degree in 2002 and a doctorate in nuclear physics in 2005 (La fermeture de sous-couche N = 16), which he did at the Institute for fundamental physics (Institute of research into the fundamental laws of the Universe, IRFU, CEA - Saclay ). As a post-graduate student , he was at Michigan State University's National Superconducting Cyclotron Laboratory (NSCL) . In 2006 he returned to research at the IRFU. In 2011 he completed his habilitation at the University of Paris XI. From 2017 he was at the TU Darmstadt . For 2019 he received a Humboldt Professorship .

He deals with the spectroscopy of unstable (radioactive) nuclei, for which he developed new methods. From 2010 he investigated short-lived nuclei with in-beam gamma spectroscopy at the RIBF of the RIKEN. The MINOS Vertex Tracker was developed for this purpose (a target container made of liquid hydrogen with a compact trace drift chamber ). Obertelli was looking, among other things, for exotic seeds with new magic numbers . In Darmstadt he is the spokesman for the PUMA experiment (antiProton Unstable Matter Annihilation), in which neutron skins and halos around neutron-rich, medium-weight nuclei (as an example of low-density neutron matter) are examined with antiprotons.

In 2010 he received an ERC Starting Grant and in 2018 an ERC Consolidator Grant (endowed with 2.5 million euros over five years). In 2013/14 he received a scholarship from the Japan Society for the Promotion of Science at RIKEN . He is on the user executive committee of the Radioactive Isotope Beam Factory (RIBF) of the RIKEN and co-spokesman for the SEASTAR collaboration. From 2018 he is in the scientific council of the R3B (reactions with relativistic radioactive rays) project group at FAIR in Darmstadt. He is on the scientific steering committees of GANIL and the Institute for Nuclear Physics (IPN) in Orsay .
