- Descrição
- A research on ternary fission of Al, Ti, Co, and Zr nuclei induced by bremsstrahlung photons of 0.8, 1.0, 1.4, and 1.8 GeV end-point energies has been carried out using makrofol polycarbonate and CR-39 polymer as fission-track detectors. Thick target metal foils were used in contact with the plastic detectors. From the observation and analysis of double divergent, etched fission tracks from a common point inside the target the number of events of ternary fission has been evaluated. Absolute mean cross sections per photon of ternary fission in the range 0.8-1.8 GeV have been obtained as <math>0.3 \pm 0.7, </math> <math> 1.7\pm 1.5 , </math> <math> 0.5\pm 0.5</math> , and <math>1 \pm 1\mu b </math>, respectively, for Al, Ti, Co, and Zr nuclei. A probability of ternary fission of <math>\sim 10 ^{-4}\,\!</math> has been deduced. Results are discussed and compared with other ternary fission data.
