Query: Observation of molecules produced from a Bose-Einstein condensate   Molecules are created from a Bose-Einstein condensate of atomic 87Rb using a
Feshbach resonance. A Stern-Gerlach field is applied, in order to spatially
separate the molecules from the remaining atoms. For detection, the molecules
are converted back into atoms, again using the Feshbach resonance. The measured
position of the molecules yields their magnetic moment. This quantity strongly
depends on the magnetic field, thus revealing an avoided crossing of two bound
states at a field value slightly below the Feshbach resonance. This avoided
crossing is exploited to trap the molecules in one dimension.
