Article Synopsis
- Most research on ionizing radiations in cancer treatment has primarily focused on the ionization process, overlooking the effects of excitation events.
- This study utilizes a novel cathodoluminescence system to analyze the excited states of DNA when exposed to accelerated electrons in the picosecond time frame.
- Findings indicate both qualitative differences and quantitative similarities between DNA's excited states under electron and photon exposure, highlighting the importance of understanding these processes.
The photodissociation dynamics of CHI and CHClI at 272 nm were investigated by time-resolved Coulomb explosion imaging, with an intense non-resonant 815 nm probe pulse. Fragment ion momenta over a wide / range were recorded simultaneously by coupling a velocity map imaging spectrometer with a pixel imaging mass spectrometry camera. For both molecules, delay-dependent pump-probe features were assigned to ultraviolet-induced carbon-iodine bond cleavage followed by Coulomb explosion.

At harmonic order 17, we observe a minimum in the amplitude of the emitted spectrum and a corresponding distortion in the phase. Our experimental results are compared to two models: a multicenter interference model focused on the effect of the structure of the SF6 molecule in HHG and a model focused on the interferences between multiple ionization channels in HHG.
