About half the original atoms in the condensate seem to have vanished in that they are not seen in either the remnant or the expanding gas cloud.
I hope the spectra of radiation they are checking include the gamma and x-ray bandwidths, or they may get some very sick physicists. Or may be neutrons: what happens to the electrons in cases where their energy level is this low?
