本文研究了磁囚禁气体中Li-7的玻色-爱因斯坦凝聚。由于Li-7原子之间的有效吸引作用，多体量子理论预测凝聚体的占据数被限制在大约1400个原子。我们观察到凝聚数被限制在a;最大值在650和1300个原子之间。测量使用一种通用的相衬成像技术。
Bose-Einstein condensation of Li-7 has been studied in a magnetically trapped gas. Because of the effectively attractive interactions between Li-7 atoms, many-body quantum theory predicts that the occupation number of the condensate is limited to about 1400 atoms. We observe the condensate number to be limited to a;maximum value between 650 and 1300 atoms. The measurements were made using a versatile phase-contrast imaging technique.
