Vremenski razvoj intermetalnih difuznih spektara

LiZn and LiCd vapour mixtures prepared in the heat-pipe oven are irradiated with pulsed excimer laser emission at 308 nm. Temporal evolution of the fluorescence spectra is observed showing that different processes occur such as multiphoton excitation, collisional energy transfer, photochemical reaction, relaxation etc. Temporal change of the LiZn and LiCd blue-green diffuse bands spectral shape is observed and interpreted in terms of previous spectral simulations. The effective lifetimes of different spectral features are determined.Mješavine para Li-Zn i Li-Cd pripremili smo u toplovodnim pećima i obasjavali pulsnim excimerskim laserom na 308 nm. Opažanje vremenskog razvoja fluorescentnih spektara pokazalo je postojanje različitih procesa kao što je multifotonska pobuda, sudarni prijenos energije, fotokemijska reakcija, relaksacija itd. Opaženu vremensku promjenu spektralnog oblika plavo-zelenih difuznih vrpci LiZn i LiCd molekula objasnili smo pomoću ranijih svojstava spektralnih simulacija. Odredili smo efektivna vremena života različitih spektralnih pojava

Production and deceleration of a pulsed beam of metastable NH (a1Δa ^1\Delta) radicals

We report on the production of a pulsed molecular beam of metastable NH ($a ^1\Delta$) radicals and present first results on the Stark deceleration of the NH ($a ^1\Delta, J=2, M\Omega=-4$) radicals from 550 m/s to 330 m/s. The decelerated molecules are excited on the spin-forbidden $A ^3\Pi \leftarrow a ^1\Delta$ transition, and detected via their subsequent spontaneous fluorescence to the $X ^3\Sigma^{-}, v"=0$ ground-state. These experiments demonstrate the feasibility of our recently proposed scheme [Phys. Rev. A 64 (2001) 041401] to accumulate ground-state NH radicals in a magnetic trap.Comment: 11 pages, 4 figures, v2: fixed author name for web-abstract, no changes to manuscrip
