Vol. 63 032516 (2001) DOI: 10.1103/PhysRevA.63.032516 | | Subject: | Atomic Physics; Chemical Physics | physics.atom-ph physics.chem-ph | | Abstract: | Absorption of radiation from the sodium dimer molecular states correlating to Na(3s)-Na(3s) is investigated theoretically. Vibrational bound and continuum transitions from the singlet X Sigma-g+ state to the first excited singlet A Sigma-u+ and singlet B Pi-u states and from the triplet a Sigma-u+ state to the first excited triplet b Sigma-g+ and triplet c Pi-g states are studied quantum-mechanically. Theoretical and experimental data are used to characterize the molecular properties taking advantage of knowledge recently obtained from ab initio calculations, spectroscopy, and ultra-cold atom collision studies. The quantum-mechanical calculations are carried out for temperatures in the range from 500 to 3000 K and are compared with previous calculations and measurements where available. | | Source: | arXiv, physics/0008060 | | Services: | Forum | Review | PDF | Favorites | |
