Current prospects on Low Energy Particle Track Simulation for biomedical applications

Integral cross sections for electron impact excitation of vibrational and electronic states in phenol

“…1 are the threshold energies for each of the composite vibrational-modes investigated. 21 Threshold energies are important quantities in simulation studies [11][12][13][14][15][16][17][18] and as such are denoted here for information purposes. It is clear that the ICS energy dependencies, for each of the modes, are very similar, to within the errors quoted.…”

“…21,23 Nonetheless, when simulating atmospheric plasma behaviour, etc., it is actually the integral cross sections (ICSs) (and the momentum transfer cross section) that are of most relevance to the modelling communities. [11][12][13][14][15][16][17][18] As a consequence, in this short paper, we report on our derivation of vibrational-mode and electronicstate ICSs from our previously published differential cross section measurements. 21,22 Phenol also possesses a range of physico-chemical properties which, from our experience with other collision systems, [24][25][26][27][28][29][30] are anticipated to play important roles in its scattering dynamics.…”

“…5,6 Plasmas have, therefore, also been investigated to remove phenolic based species from wastewater as a remediation strategy. [7][8][9][10] In order to gain a fundamental understanding for the utility of atmospheric plasmas to economically produce bio-fuels and other useful chemicals, or degrading toxic compounds, plasma simulations incorporating complete cross section databases (in fact, this is true in modelling most phenomena [11][12][13][14][15][16][17][18] ) are required. To this end, we have conducted a series of joint experimental and theoretical studies looking at the behaviour of electron-phenol scattering processes.…”

Total electron-scattering cross sections from pyrimidine as measured using a magnetically confined experimental system

“…In this respect our IAM-SCARD formalism has proven to be an extremely helpful complement to the experiment for providing CSs σ − σ forw emulating the exact experimental conditions so that a realistic comparison could be achieved. Certainly, the measurements present one step further towards the availability of a benchmarked selfconsistent pyrimidine data base for simulation [29] or other purposes. However, although the apparatus in its present form shows utility for total cross-section measurements, we aim to develop it further to achieve a better energy (and thus angular) resolution (or near constant resolution of approximately the lowest values obtained here, 0.4 eV-this would translate to an angular resolution of 1.6 • -13 • for energies between 500 and 8 eV) before performing integral elastic, inelastic, or differential CS measurements.…”

Intermediate energy electron impact excitation of composite vibrational modes in phenol

“…[1][2][3][4][5][6][7] Of special note, particularly for vibrational excitation and DEA, is when the incident electron is temporarily captured by the target species, leading to the formation of resonances, 8 which can lead to a significant enhancement in the magnitude of the scattering cross sections, [8][9][10][11] than would otherwise be the case, and/or promote DEA. Indeed, it is well known that this resonance behaviour plays a lead role in the dynamics driving the electron-initiated processes in some of those applications (e.g., Ref.…”
