A METHOD TO DETERMINE THE CHARGE OF PARTICLES STOPPING IN NUCLEAR EMULSIONS
An investigation is described oi a photometric method for the determination of the charge of particles stopping in nuclear emulsions. The image of the track in the emulsion was projected cn a narrow- slit plaeed in front of a photomultiplier and moved perpendicularly across the slit. The slit was parallel to the direction of the track and the absorption of light was measured by means of the photomultiplier and a recording instrument. The resolving povaer depends on the available track length, the quality and the degree of development of the emulsions. If track lengths of 100 mu are used in normally developed G 5 emulsions of good quality it is possible to separate doubly and singly charged particles in about 95% of the cases, the resolution being better for multiply charged particles.
