Abstract
WHILE studying the influence of liquids1 on the tribo-excited emission phenomena of exo-electrons (Kramer effect2) from metals, we have found that the amphoteric metals like aluminium, zinc and tin as well as brass and some soldering alloys containing tin give a comparatively strong emission of exo-electrons when irradiated with visible light, after the freshly abraded surface is sprayed with strong concentrated sodium hydroxide or potassium hydroxide.
