We report on the production of a pulsed molecular beam of metastable NH ($a ^1Delta$) radicals and present first results on the Stark deceleration of the NH ($a ^1Delta, J=2, MOmega=-4$) radicals from 550 m/s to 330 m/s. The decelerated molecules are excited on the spin-forbidden $A ^3Pi leftarrow a ^1Delta$ transition, and detected via their subsequent spontaneous fluorescence to the $X ^3Sigma^{-}, v=0$ 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.
We report on the Stark deceleration and electrostatic trapping of $^{14}$NH ($a ^1Delta$) radicals. In the trap, the molecules are excited on the spin-forbidden $A ^3Pi leftarrow a ^1Delta$ transition and detected via their subsequent fluorescence to
We report on the Stark deceleration of a pulsed molecular beam of NO radicals. Stark deceleration of this chemically important species has long been considered unfeasible due to its small electric dipole moment of 0.16 D. We prepared the NO radicals
We have used a commercial RF ion-source to extract a beam of metastable neon atoms. The source was easily incorporated into our existing system and was operative within a day of installation. The metastable velocity distribution, flux, flow, and effi
We study the dynamics of a supersonic molecular beam in a low-finesse optical cavity and demonstrate that most molecules in the beam can be decelerated to zero central velocity by the intracavity optical field in a process analogous to electrostatic
We investigate the ultracold reaction dynamics of magnetically trapped NH($X ^3Sigma^-$) radicals using rigorous quantum scattering calculations involving three coupled potential energy surfaces. We find that the reactive NH + NH cross section is dri
