| Abstract: | Based on Bose-Einstein condensation at minimized momentum state, a criterion for the validity of potential and the limited atom number loaded in a power law attractive potential well for ultra-cold atom gas is deduced. The criterion gives the required potential intensity when the loaded atom number is defined, or the limited atom number when the potential intensity is decided. |
