Area of Science:

  • Nuclear physics
  • Radiation transport

Background:

  • Green's function methods are crucial for high-charge, high-energy (HZE) ion transport calculations.
  • Advancements in perturbation series and nonperturbative techniques have improved practical implementation.

Purpose of the Study:

  • To extend nonperturbative methods to inhomogeneous media for simulating lead scattering foils.
  • To validate transport codes and databases against experimental data for applications in cancer therapy and space exploration.

Main Methods:

  • Developed a closed-form solution using multiple fragmentation perturbation series.
  • Applied nonperturbative techniques for effective summation of the solution.
  • Extended methods to inhomogeneous, two-layer transport media.
  • Utilized Langley Research Center's atomic and nuclear database.
