Abstract

An energy correction method is described to account for the Breit and QED effects on Auger electrons and X-ray energies in the recently developed atomic relaxation model BrIccEmis. The results are compared with literature and new experimental data for Z = 52. Overall this improves the agreement of the calculated energies with the literature values. A new atomic radiation database NS_Radlist, will contain atomic transition energies from the BrIccEmis program with these energy corrections.

Highlights

  • Highly-targeted cancer therapy requires a very localized radiation source that selectively causes damage to the cancer cells while leaving the surrounding healthy cells unaffected

  • Note that in BrIccEmis the calculated energies were obtained in the j j coupling framework while the Auger energies in Larkins’ tabulation are obtained in the intermediate coupling framework

  • The multiplet splitting depends on the coupling scheme used

Summary

Introduction

Highly-targeted cancer therapy requires a very localized radiation source that selectively causes damage to the cancer cells while leaving the surrounding healthy cells unaffected. An energy correction method is described to improve the energies calculated by the RAINE code for use in BrIccEmis and the results are compared with the most comprehensive compilation of Auger-electron energies for singly-ionized atoms [14] and the experimental data. This correction is one of the major improvements implemented in BrIccEmis to be used for the construction of a new database. This database, named NS_Radlist [15], will be suited for a wide range of applications, including dosimetry simulations
