在液氩中，由…cap - α产生的闪烁和电离。粒子和裂变碎片被测量为外加电场的函数（小于或等于38千伏/厘米）。高激发密度引起的猝灭与场无关。>4千伏/厘米…粒子。闪烁是由于…粒子的最大电流约为1.5 kV/cm。在低场中，闪烁的增加（2.5 +- 0.7%）迄今尚未观察到，这归因于零场中淬火过程的存在。
The scintillation and ionization yields in liquid argon by ..cap alpha.. particles and fission fragments have been measured as a function of the applied electric field (less than or equal to38 kV/cm). The quenching due to high excitation density does not depend on the field for approx. >4 kV/cm for ..cap alpha.. particles. The scintillation due to ..cap alpha.. particles shows a maximum at about 1.5 kV/cm. This increase (2.5 +- 0.7%) of the scintillation at low fields has not been observed heretofore and is ascribed to the presence of a quenching process at zero field.
