Shifts of hydrogen lines from electron collisions in dense plasmas

Journal Article · · Phys. Rev. A; (United States)
The semiclassical impact-parameter method is used to calculate shifts of Lyman and Balmer lines from levels n< or =6 caused by electrons in a dense plasma. Comparison with measurements and estimates of shifts due to ion quadrupole interactions indicate that shifts from distant electron-atom collisions are the major cause of observed shifts of Balmer lines. Blue shifts from ion-atom quadrupole interactions are relatively small for low series members.
