- Descrição
- Quasi-monochromatic photon beams of 108-MeV Compton-edge energy produced in the ROKK-1M facility at the storage ring VEPP-4M (BINP, Novosibirsk) and makrofol sheets as fission track detectors have been used to measure the photofission yield of <math>^{27}Al\,\!</math>. The fission yield was found <math>(160\pm 55) \mu b\,\!</math>. From the present result and previously measured <math>^{27}Al\,\!</math> photofission yield at <math>\sim 79\,\!</math> MeV end-point energy with the LADON apparatus, the trends of fission cross section and fissility have been obtained in the incident photon energy range <math>\sim 40-110\,\!</math> MeV. The present results and data for other intermediate-mass nuclei obtained with the same methodolgy have indicated an increase of fissility with decreasing <math>Z^2/A\,\!</math> as predicted by the liquid-drop model for fissioning systems lighter than <math>\sim \,\!</math> Ag.
