Rossi, B.; Nereson, N.;
Experimental Determination of the Disintegration Curve of Mesotrons
Phys. Rev. 62 (1942) 417;

The disintegration curve of mesotrons has been experimentally determined by investigating the delayed emission of disintegration electrons which takes place after the absorption of mesotrons by matter. Within the experimental errors, the disintegration curve is exponential and corresponds to a mean lifetime of 2.3 0.2 microseconds.
