实验测定了沿最小电离粒子轨迹形成的电离团簇中的电子数分布。给出了Ar、He、甲烷、乙烷、丙烷、异丁烷和二氧化碳的结果，即漂移室中通常用作计数气体的气体。发现形成含电子团簇的几率w(N)随n的增大而单调递减。W(1)的典型值为0.66(Ar)、0.77(He)和0.79(CH4)。将计算结果与模型预测结果进行了比较。
The distribution of the number of electrons contained in the ionization clusters formed along the track of minimum ionizing particles has been determined experimentally. Results are presented for argon, helium, methane, ethane, propane, isobutane and carbon dioxide, i.e., for gases which are commonly used as counting gases in drift chambers. The probabilitiesw(n) for the formation of a cluster containingnelectrons were found to be monotonically decreasing for increasingn. Typical values forw(1) are 0.66 (Ar), 0.77 (He), and 0.79 (CH4). The results are compared with model predictions.
