Abstract
The energy deposition (stopping) cross section for alpha particles ( 3He2+) on a formaldehyde molecule is calculated, using Electron Nuclear Dynamics, over the projectile energy range of 0.1 to 250 keV/amu. The differences with respect to the orientation of the target molecule with respect to the projectile beam, and the contributions from electronic, nuclear, and rovibrational stopping are discussed.
