Beschreibung
The interaction of fast ions with molecules of biological interest is a topic of unceasing research interest due to its inherent application to radiation damage of biological tissue [1]. Additionally, such collision systems provide stringent tests for advanced distorted-wave collision theories [2]. Here we report measurements of electron DDCS spectra obtained at zero-degree emission angle with respect to the ion beam from collisions of 11 MeV H-like and He-like boron ions with CH4 molecules. Theoretical DDCS spectra resulting from CDW and CDW-EIS theories along with their respective variants are critically compared to the measurements. While both theories show good overall agreement, specific differences and features observed in the cusp and BEe peak regions provide a basis for further discussion regarding the theories considered.
