Tl$sup +$离子通过电子碰撞的单电离的绝对截面已被测量为电子能量的函数，从低于阈值到约2000 eV。发现在约100 eV的入射电子能量下，横截面从阈值处和阈值以下的零值增加到约1.7 x 10 $sup-16 $cm$sup 2$的最大值。测量是在一个交叉束设施中操作的脉冲束模式。进行了多次一致性检查，以评估实验误差的可能来源。（AIP）
Absolute cross sections for the single ionization of Tl$sup +$ ions by electron impact have been measured as a function of electron energy from below threshold to approximately 2000 eV. It was found that the cross section increased from a zero value at and below threshold to a maximum value of about 1.7 x 10$sup -16$ cm$sup 2$ at an incident electron energy of approximately 100 eV. Measurements were made in a crossed-beam facility operating in the pulsed- beam mode. Numerous consistency checks were performed to evaluate possible sources of experimental error. (AIP)
