Analysis of Optically Excited Mercury Molecules

Analysis of Optically Excited Mercury Molecules

Date: January 1975
Creator: Drullinger, R. E.; Hessel, M. M. & Smith, E. W.
Description: Report presenting new measurement techniques used to obtain potential curves, f-values, and kinetic behavior for Hg2. The Hg2 molecule is representative of a class of molecules which have dissociative ground states and bound excited states. It can therefore be used as a prototype of this class of molecules which are of interest as potential new laser candidates. Because of the non-bound ground state, standard absorption spectroscopic techniques cannot be used to obtain the necessary information about the excited states.

The Calculation of Rotational Energy Levels and Rotational Line Intensities in Diatomic Molecules

The Calculation of Rotational Energy Levels and Rotational Line Intensities in Diatomic Molecules

Date: June 1970
Creator: Hougen, Jon T.
Description: Report describing procedures for making quantum mechanical calculations of rotational energy levels and rotational line intensities in diatomic molecules. The procedures are illustrated by sample calculations. A familiarity with the material of this report should enable a practicing electronic spectroscropist to carry out, though in a rather mechanical way, his own theoretical calculations for molecules under experimental investigation.

The Effect of Time Ordering on the Lyman α Profile

The Effect of Time Ordering on the Lyman α Profile

Date: June 1971
Creator: Godgrey, J. T.; Vidal, C. R.; Smith, E. W. & Cooper, J.
Description: Report investigating the effects of time-ordering over the complete line profile using a unified theory of spectral line broadening previously developed. The behavior of the time-ordered thermal average and un-time-ordered thermal average are compared. The Fourier transform of the thermal average is obtained analytically. Calculations for the line profile of the Lyman-[functional symbol alpha] line of hydrogen are presented and are representative in that the full thermal average is replaced by the thermal average with the electron velocity distribution approximated by f(v)=[functional symbol alpha] (v-vav) where vav is the thermal velocity for the plasma in question.

The First Spectrum of Hafnium (HF I)

The First Spectrum of Hafnium (HF I)

Date: July 1976
Creator: Meggers, William F. & Moore, Charlotte E.
Description: Report continuing W. K. Meggers' previous analysis in LS-coupling. This coupling is not rigorous in Hf I, and many intervals are irregular. Consequently, the levels are given also in numerical order with the even and odd levels presented in separate tables. The long line lists are given in two Appendices: Appendix A contains the observed Zeeman data for the individual lines, 531 in all; Appendix B consists of the complete line list of observed and classified lines. By far the greater part of the analysis is that of Meggers.
