Polarization of Healpha radiation due to anisotropy of fast-electron transport in ultraintense-laser-produced plasmas.

An atomic kinetics code is developed to gain insight into the generation of polarized Healpha by fast electron transport relevant to fast ignition. The calculation predicts a very small polarization in the dense region (>or=100 times the critical density) due to frequent elastic transitions between magnetic sublevels, while high polarization is observable in the low density region ( View Article and Find Full Text PDF
