结合直接测量的或由电荷分布计算的独立产额，研究了12- 30 MeV韧致辐射引起的235/U的Kr、Rb、Sr、Sn、Sb、Te、Sr、Cs和Ba同位素分布。在相同的韧致辐射端点能量下，研究了/sup 238/U光裂变的Rb、Sn、Sb、Te、I和Xe同位素分布。对于这两个裂变系统的锡分布显着比所有其他分布更广泛。从元素产率计算质子奇偶效应作为Z的函数。结果几乎是零。
Combining independent yields directly measured or calculated from the charge distribution, the Kr, Rb, Sr, Sn, Sb, Te, Xe, Cs, and Ba isotopic distributions were investigated for the 12--30-MeV bremsstrahlung-induced photofission of /sup 235/U. At the same bremsstrahlung endpoint energies the Rb, Sn, Sb, Te, I, and Xe isotopic distributions were studied for the photofission of /sup 238/U. For both fissioning systems the tin distributions were significantly broader than all other distributions. From the elemental yields the proton odd-even effects were calculated as a function of Z. They turned out to be almost zero.
