DIAMETER OF ETCHED FISSION FRAGMENT TRACKS IN SOLID STATE NUCLEAR TRACK DETECTORS AS A FUNCTION OF PARTICLE ENERGY

Glass and several plastic materials have been irradiated orthogonally with respect to their surfaces by 235U fission fragments of known mass and energy. A correlation between fragment energy and the diameters of the etched fragment tracks is given. For sufficiently long etching times the method is well capable of an energy resolution of about 3 to 5 MeV. A weak mass dependence of this effect is existing. To test the methos a 252Cf fission fragment energy distribution has been measured which is in good agreement with corresponding solid state surface barrier detector. © 1969.
