Sub-Doppler features of optical processes in the Rb extremely thin cell filled with an additional buffer gas.
2009
International audience; Comparison of the resonant absorption and fluorescence in the extremely thin cell (ETC) filled with pure Rb with another one filled with Rb and Neon gas with the pressures 6 Torr and 20 Torr is provided. The effect of the collapse and revival of Dicke-type narrowing is still observable for the thickness L=λ/2, and L=λ, where λ is a resonant laser wavelength 794 nm (D1 line of the Rb), i.e. the spectra of the resonant absorption and fluorescence demonstrate the sub-Doppler narrowing for the thickness L=λ/2 and broadening for the thickness L=λ. It is important to note, that in an ordinary Rb cell with the thickness L in the range of 1mm- 10 cm filled with buffer gas, w…

Quantum dynamics study of rate constant for a reactive collision of astrophysical interest : the D+ + H2 reaction
2014
For chemistry networks describing the reactions for the early universe and especially for accuratemodels of the enrichment of deuterated molecules observed, we need to know in detail manystate-to-state rate coeffcients. Today most of the rate coeffcients of interesting reactions are stillunknown or with a poor accuracy. For example, the uncertainty about the rate coeffcient for thereaction directly affects model predictions for the HD abundance and thereby the cooling rate ofthe primordial gas. It is therefore of astrophysical importance to determine an accurate value ofthese rates, and helping to understand the cooling requires a complete set of the state-to-state ratecoefficients as well …
