TL;DR: A general scheme for sympathetic cooling of molecules to microK temperatures on a timescale of seconds and the measurement of the role of laser-induced molecular alignment on the dipole force in optical Stark deceleration to outline progress towards the realisation of chirped optical StarkDeceleration for producing slow molecular beams with mK energy spreads.

TL;DR: In this paper, a theoretical model for isotopologues of beryllium monohydride, BeH, BeD and BeT, A (2)Pi to X (2)-Sigma(+) visible and X(2)Sigm(+) to X 2 -Sigma (+) infrared rovibronic spectra is presented.

TL;DR: In this paper, the authors proposed a hybrid variational-perturbation method for the calculation of rotation-vibration states of medium sized molecules, which combines the advantages of variational calculations and perturbation theory.

TL;DR: In this paper, the R-matrix method is employed as it is very efficient for characterizing the many resonances found in electron-ion collisions, and positions, widths and symmetries are obtained for the lowest ten Feshbach resonances for each ion.

TL;DR: In this paper, the authors present new Rosseland mean opacities for a hydrogen-helium gas of 1000 K ≤ T ≤ 9000 K and -14 ≤[ρ (g cm-3)] ≤ -2.
