Journal article (other academic/artistic)abstract
- We measured damage cross sections of the peptide LHRH for various MeV ions with the same velocity and compared the data with simple hit theory calculations. We employed scanning force microscopy to measure dimensions of surface tracks in amino acid L-vali

Journal article (other academic/artistic)abstract
- We measured the electronic-stopping-power dependences of mega-electronvolt atomic-ion-induced sputtering and cratering of bio-organic targets. We employed a collector method to study relative total yields of sputtered intact peptide molecules and scanning
