Abstract

The temperature and density of the Bose-Einstein condensate was determined using two-photon spectroscopy of the 1s-2s line, through studies of the collisionally shifted and broadened spectral lines. The complex-scaling method was used to determine the autoionization widths. Perturbation theory was used to obtain the asymptotic expressions for the interaction energies, for nuclear separation larger than 22 atomic unit.
