We present calculations of the properties of bubbles in liquid helium-4 containing 3 or 8 electrons. The pressure range in which these bubbles are stable is determined. For Z =3, we find that the bubbles are unstable except in a pressure range between − 0.78 and − 0.90 bars. For Z = 8, the bubbles are stable provided the pressure is in the range from zero to – 0.42 bars. At the upper end of the pressure range, the bubbles break into smaller bubbles each containing a fraction of the electrons; at the lower end the bubbles become unstable against unlimited expansion.

超流氦 4 中少电子气泡的性质

我们计算了含有 3 或 8 个电子的液氦 4 中气泡的性质。确定这些气泡稳定的压力范围。对于 Z = 3，我们发现气泡是不稳定的，除非在 - 0.78 和 - 0.90 巴之间的压力范围内。对于 Z = 8，如果压力在 0 到 – 0.42 巴的范围内，气泡是稳定的。在压力范围的上限，气泡分裂成更小的气泡，每个气泡都包含一小部分电子；在低端，气泡变得不稳定，无法无限膨胀。
