在超冷温度（$T 140$与$n=90$时的$1\，\mu\text {s}$相比）下的稠密环境（$\rho \approximately 10^{14}\，$atoms/cm$^3$）中。此外，还研究了第二种反应机理，即Rb$_2^+$分子的形成。当n=40$时，两种反应产物的几率相等，但当n = 90 $时，生成的Rb 2 ^+$的比例下降到10%以下。
Within a dense environment ($\rho \approx 10^{14}\,$atoms/cm$^3$) at ultracold temperatures ($T 140$ compared to $1\,\mu\text{s}$ at $n=90$. In addition, a second observed reaction mechanism, namely Rb$_2^+$ molecule formation, was studied. Both reaction products are equally probable for $n=40$ but the fraction of Rb$_2^+$ created drops to below 10$\,$% for $n\ge90$.
