Abstract: 
We study the energy loss of helium and hydrogen ions after transmission through monolayers of graphene and MoS₂ and compare experimental results with different computational approaches. We find a systematically higher energy loss in experiments compared to simulations by up to a factor of 2. Additionally, our results show that neutralization processes of the particles increase the kinetic energy loss, a contribution generally not included in any computational approach.
