The Ionization Mechanism in Radioactive Ionization Detector

The Journal of the Society of Chemical Industry, Japan, 1965
放射線イオン化検出器の分野では,イオン化ポテンシャル(以下1.P・と略す)が,アルゴンの励起状態の原子の11.6eVよりも低い一般の有機ガスの場合を除いて,イオン化機構に関する研究がほとんどされていない。著者らは先の報文で,RaD100μcのα線源を内蔵する放射線イオン化検出器を用いた無機ガスの分析に関する報告を行なった。この研究の一環として,この報文ではI.P.が11.6eV以上のサソプルガスとして,モレキュラーシーブ5Aカラムのガスクロマトグラフィーで,空気から分離した酸素と窒素を用い,キャリヤーガスに,アルゴン,有機蒸気を含れアルゴン,ヘリウムおよび水素を用いた場合の実験結果を考察して,“Penning効果”,加速電子およびα 線による直接のイオン化 ...
