Experimental and Theoretical Analysis of Central Asymmetry
- Conference date: 15–20 June 2008
- Location: Valladolid (Spain)
The hydrogen Balmer beta line is used as a plasma diagnostics tool for a long time. It is well known that the experimental profiles of line exhibit an asymmetry while some of most commonly used theoretical models, due to the employed approximations, give unshifted and symmetrical profiles [1, 2]. In the present work the central part of profile is reanalyzed experimentally and in terms of two theoretical approaches based correspondingly on the Standard Theory (ST) assumptions  and on the electric field computer simulation method [4, 5]. The present experimental and theoretical results are compared with the obtained earlier experimental [6–12] and theoretical data .
