Sa. Karamian et al., Light-mass yields and fine structure of mass distributions in Th-232 photofission - art. no. 024601, PHYS REV C, 6202(2), 2000, pp. 4601
Fission-fragment mass distributions in the Th-232(gamma, f) reaction have b
een measured from the cumulative yields of radionuclides following activati
on at bremsstrahlung endpoint energies E-e = 7.5, 12.0, and 24.0 MeV. The y
ields of the light nuclei Na-24 and Mg-28 were detected following activatio
n at E-e = 16.5 and 24.0 MeV. Energy dependences of the symmetric mode and
light nuclide yields are discussed. Fine-structure manifestations near asym
metric and symmetric masses were observed.
