The Hanle Effect of the Hydrogen Ly-alpha Line for Probing the Magnetism of the Solar Transition Region
Hanle Effect Hydrogen Ly-alpha Line Solar Transition Region
2011/8/18
Abstract: We present some theoretical predictions concerning the amplitude and magnetic sensitivity of the linear polarization signals produced by scattering processes in the hydrogen Ly-alpha line of...
Absolute absorption on rubidium D1 line: including resonant dipole-dipole interactions
Absolute absorption rubidium D1 line resonant dipole-dipole interactions
2011/8/4
Abstract: Here we report on measurements of the absolute absorption spectra of dense rubidium vapour on the D1 line in the weak-probe regime for temperatures up to 170 C and number densities up to 3 \...

2011/9/14
New laboratory measurements using an Electron Beam Ion Trap (EBIT) and an x-ray microcalorimeter are presented for the n=3 to n=2 Fe XVII emission lines in the 15 ?to 17 ?range, along with new theoret...
Absorption Line Profile of the 5S2o-5P1 Transition of Atomic Oxygen and Its Application to Plasma Monitoring
Line Profile Atomic Oxygen 5S2o-5P1 Transition
2009/9/4
The line profile of the 5S2o-5P1 transition of atomic oxygen was measured by diode laser absorption spectroscopy. As a result, it was found that the absorption line profile had a wing component in the...
