Times Cited Count:2 Percentile:16.76(Chemistry, Inorganic & Nuclear)The reaction yields of 63 radionuclides with the mass number A = 56-135 produced in the photofission of Bi by bremsstrahlung of end-point energies (E
) from 450 to 1100 MeV have been measured using a catcher foil technique. The charge distribution was well reproduced by a Gaussian function with the most probable charge (Z
) expressed by Z
= RA + S, and with the A-independent FWHME
. The charge distribution parameters R, S and FWHM
were independent of E
above 600 MeV. The weighted mean values at E
600 MeV were R = 0.421
0.001, S = 0.6
0.1 and FWHM
= 2.1
0.1 charge unit (c.u.). Based on the charge distribution parameters, the symmetric mass yield distributions with the most probable mass A
of 96
1 mass unit (m.u.) and the width FWHM
of 33
1 m.u. were also obtained. The characteristics of the charge and mass yield distributions are discussed by referring to those for
Au based on the results of calculations using PICA3/GEM.
