New ways of obtaining cold atoms and molecules

An analysis is made of the possibility of utilizing resonance photodissociation of van der Waals complexes (with a binding energy of <0.1 eV per molecule), and resonance desorption and acoustodesorption of adsorbed molecules bound to the surface by the weak van der Waals interaction in generating fluxes of cold atoms and molecules.

Towards magnetic trapping of molecules

Břetislav Friedrich, Robert deCarvalho, Jinha Kim +3 more

The advent of buffer-gas loaded magnetic traps for atoms has opened the possibility of trapping paramagnetic molecules. We survey our results on the loading, trapping and spectroscopy of Eu atoms that demonstrated the technique. The principles governing molecular trapping considering in particular the O2 and NO systems are outlined. The trapping of molecules should prove particularly useful in spectroscopy, especially ultra-high resolution spectroscopy that requires cold (slow), trapped (long interaction time) samples. Similar to cold atoms, cold molecules could be interrogated at a level of detail which is likely to provide new insights into their structure and interactions.The advent of buffer-gas loaded magnetic traps for atoms has opened the possibility of trapping paramagnetic molecules.

Gaseous atoms or molecules: what happens at ultra-low temperature?

Masatoshi Kajita

As an introduction, the states of atoms and molecules are introduced. At room temperature, gaseous atoms and molecules move very fast. We imagine that the gaseous phase is transformed to liquid or solid phase by cooling, but it is possible only with high density of atoms and molecules. With low densities, atoms and molecules also stay in the gaseous state at low temperature. Research using cold atoms and molecules, trapped by electric or magnetic field, give important information to develop new physics.As an introduction, the states of atoms and molecules are introduced.
