Research with CRYRING@ESR

The talk will discuss a new UHV chamber being developed for the CRYRING collaboration. The chamber is being designed to accommodate atomic and nuclear physics applications. The talk will focus on low energy (~MeVs/u) nuclear charge particle reaction studies applied to nuclear astrophysics research.

Astrophysical ices are exposed to ionic projectiles from galactic cosmic rays, Solar wind, shock waves or ions trapped in the magnetospheres of giant planets. Induced radiation effects include sputtering, amorphisation and compaction, dissociation of molecules, and formation of new molecular species after radiolysis and by implantation of reactive ions. We present recent results on radiolysis...

A new relativistic method based on the Dirac equation for calculating fully differential cross sections for ionization in ion-atom collisions is developed. The method is applied to ionization of the atomic hydrogen by antiproton impact, as a non-relativistic benchmark. The fully differential, as well as various doubly and singly differential cross sections for ionization are calculated....
