Abstract: | 7 Li has been studied in a magnetically trapped gas. Many-body quantum theory predicts that the occupation number of the condensate
is limited to about 1400 atoms because of the effectively attractive interactions between 7Li atoms. Using a versitile phase-contrast imaging technique, we experimentally observe the condensate number to be consistent
with this limit. We discuss our measurements, the current theoretical understanding of BEC in a gas with attractive interactions,
and future experiments we hope to perform.
