Helmuth Kulenkampff
Encyclopedia
Helmuth Kulenkampff was a physicist notable for his studies of X-rays. He obtained his PhD in 1922 under Ernst Wagner
at the University of Munich with a thesis entitled: Über das Kontinuierliche Röntgenspektrum (On the continuous X-ray spectrum).
In 1937, Alfred Ehmert made the surprising observation that comic ray absorption in water is less than in air for same effective thickness. In 1938, Kulenkampff was the first to correctly explain this effect in terms of meson
decay, and this then enabled Hans Heinrich Euler
and Werner Heisenberg
to calculate an improved figure for meson
decay time.
Ernst Wagner
Ernst Wagner was born on 14 August 1876 at Hildburghausen. He first studied medicine and physics at the Universities of Würzburg, Berlin, and Munich, obtaining his doctorate under Wilhelm Röntgen in 1903. He became Privatdozent in spring 1909 and extraordinary professor in 1915 at the University...

Meson
In particle physics, mesons are subatomic particles composed of one quark and one antiquark, bound together by the strong interaction. Because mesons are composed of sub-particles, they have a physical size, with a radius roughly one femtometer: 10−15 m, which is about the size of a proton...
