New Journal of Physics Cold TiO ( X 3 1 ) – He collisions
نویسندگان
چکیده
We use laser ablation and cryogenic helium buffer-gas cooling to produce large numbers of X 11 TiO molecules at a translational temperature of 5K. We investigate their cold collisions with helium and measure elastic and inelastic scattering cross-sections. As expected for 31 molecules, which have large spin–rotation couplings, TiO’s inelastic m-changing collision cross-section is large: on the same order as its momentum transfer cross-section.

He-ThO(1Σ+) interactions at low temperatures: elastic and inelastic collisions, transport properties, and complex formation in cold 4He gas.
We present an ab initio study of cold (4)He + ThO((1)Σ(+)) collisions based on an accurate potential energy surface (PES) evaluated by the coupled cluster method with single, double, and noniterative triple excitations using an extended basis set augmented by bond functions. Variational calculations of rovibrational energy levels show that the (4)He-ThO van der Waals complex has a binding energ...
متن کاملProbing Scattering Resonances in (Ultra)Cold Inelastic NO-He Collisions.
We theoretically study inelastic collisions between NO radicals and He atoms at low collision energies, focusing on the occurrence of scattering resonances. We specifically investigate de-excitation of rotationally excited NO radicals (X (2)Π1/2, v = 0, j = 3/2, f) at collision energies ranging from 10(-3) to 20 cm(-1) and compute integral and differential cross sections using quantum mechanica...

Nano-sized titanium dioxide TiO2 powder was prepared by new wet chemical route from its precursor Titanium (IV) chloride (TiCl4) as precursor with isopropoxy alcohol in presence of nitric acid under ambient condition. Their morphologies, phase compositions and components of the TiO2 nanoparticles were characterized by transmission electron ...
متن کاملSpin polarization transfer in ground and metastable helium atom collisions
Cross sections and rate constants for total elastic, diffusion and transfer of metastability for collisions between He(11S)–He(23S) and He(11S)–He(23P) atoms over a wide range of energies and temperatures are presented. The rate constant for spin metastability excitation in He(11S)–He(23P) collision is several orders of magnitude larger than that for He(11S)–He(23S) collision at cold temperatur...
متن کاملCold and ultracold NH-NH collisions: the field-free case.
We present elastic and inelastic spin-changing cross sections for cold and ultracold NH(X (3)Σ(-)) + NH(X (3)Σ(-)) collisions, obtained from full quantum scattering calculations on an accurate ab initio quintet potential-energy surface. Although we consider only collisions in zero field, we focus on the cross sections relevant for magnetic trapping experiments. It is shown that evaporative cool...
