Description:
Base class to describe the volume of interaction for particle-matter interaction ...
Base class to describe the volume of interaction for particle-matter interaction.
Computer models like Monte Carlo or molecular dynamics / electron- or ion-beam interaction simulations can be used to qualify and (or) quantify the shape of the interaction volume. Results of such simulations can be summary statistics or single-particle-resolved sets of trajectories.
Explicit or implicit descriptions of the geometry of this interaction volume are possible:
An implicit description is via a set of electron/specimen interactions represented ideally as trajectory data from the computer simulation.
An explicit description is via iso-contour surface using either a simulation grid or a triangulated surface mesh of the approximated iso-contour surface evaluated at specific threshold values. Iso-contours could be computed from electron or particle flux through an imaginary control surface (the iso-surface) or energy-levels (e.g. the case of X-rays). Details depend on the model.
Another explicit description is via theoretical models which may be relevant e.g. for X-ray spectroscopy
Further details on how the interaction volume can be quantified is available in the literature for example:
