PHYSICAL METHOD FOR DEVELOPING TRACK PICTURES OF LOW IONIZING PARTICLES

Development of 15-Mev proton and 300-Mev pi /sup +/ meson tracks in 200 mu layers of NIKFI-R emulsion with noxyphenylglycerin physical developer was studied. It is shown that with the physical developing method it is possible to regulate the size of silver granules in the track and to improve discrimination of proton tracks from the gamma background.
