Jednostruki elektronski zahvat u sudarima brzih projektila sa vodoniku i helijumu sličnim metama

Abstract

Electron capture is a process which garners scientific interest for a number of reasons, ranging from a purely fundamental atomic physics standpoint to more practically oriented interdisciplinary applications, such as in fusion energy research and medical physics. In the present work, single-electron capture by fast projectiles from hydrogen- and helium-like targets is studied by means of the boundary-corrected continuum intermediate states method (BCIS), both in its three-body (BCIS-3B) and four-body (BCIS-4B) formulation. In this thesis, these two methods are developed for single-electron capture from the ground state of the target into arbitrary states of the projectile. General programs are constructed for the calculation of total cross sections for arbitrary projectile-target pairs, as well as differential cross sections for certain special cases. A large number of projectiletarget pairs are explored, with the obtained theoretical results being graphically represented. For almost all the considered processes, experimental data points are available for comparison. The agreement between the newly obtained theoretical results and the measurements ranges from good to nearly perfect.
