Description

The experiment was carried out at the electron accelerator (JINR, Dubna).
We studied the reaction products inside thin ${}^{238}$U sample irradiated by secondary gamma created from lead target by electron beam [1,2].
The mass distribution of uranium fission products on electron beam at energy of 140 MeV is shown in Fig. 1.

1- ${}^{78}$Ge, 2- ${}^{79}$Kr, 3- ${}^{84}$Br, 4- ${}^{85}$Kr, 5- ${}^{89}$Rb, 6- ${}^{94}$Y,${}^{94m}$Tc, 7- ${}^{97}$Zr,${}^{97}$Nb, 8- ${}^{99}$Pd, 9- ${}^{104}$Cd, 10- ${}^{105}$Rh, 11- ${}^{112}$Ag, 12- ${}^{114m}$In, 13- ${}^{117}$Sb, 14- ${}^{123}$I, 15- ${}^{127}$Sn, 16-${}^{128}$Sn, ${}^{128}$Sb, 17- ${}^{129}$Sb, 18- ${}^{130}$Sb, 19- ${}^{132}$I, 20- ${}^{133}$I, ${}^{133}$Te, 21- ${}^{134}$I, ${}^{134}$Te, 22- ${}^{135}$I, ${}^{135m}$Xe, 23- ${}^{138}$Cs, 24- ${}^{141}$Ce, ${}^{141}$Ba, 25- ${}^{142}$La, 26- ${}^{146}$Pr, 27- ${}^{149}$Nd.
