## Abstract **Low‐energy electrons** (LEEs) interact with a DNA model system to create a variety of excited states. In the gas phase, dissociative (σ\*) states are accessible by LEEs with energy <4 eV (see picture) and cause facile strand breaks through a dissociative electron attachment mechanism.
## Abstract 5‐Bromouracil‐substituted DNA was isolated form __B. Subtilis__ and phage PBSH. The three DNA fractions of Different densities (TT, TB, and BB) were irradiated with u.v. (313nm). The number of single‐strand and double‐strand breaks was determined. The breakage rates are given. It was fo
