Neues Verfahren zur Messung von Krümmung und Streuwinkeln von Nebelkammerbahnen

Summary A method is described which allows not only to determine the radius of curvature but also to recognize and eliminate impacts at angles larger than 1°, which the particle suffers in the cloud chamber gas. The size of the angles can be determined. It is shown, moreover, that the sum of the squares of the angles of scattering (for unit of length, calculated from the measured angles) is larger by a factor of 10–100 than the one calculated according to theory.
