According to the experimental data and calculations of the cross sections the fission of lanthanum results in formation of isotopes wlth surplus neutrons. The isotopes are distributed over a wide range of atomic numbers from Z = 15 to Z = 40. The yields from fission of lanthanum by 660-Mev protons distributed according to their atomic number are shown graphically. The diagram indicates the probability of symmetric and asymmetric fission. Some of the fragments have cross sections from 10/sup -30/ to 10/sup -28/ cm/sup 2 /. The total cross section is equal to 0.6 x 10/sup -27/ cm/sup 2/, which is in good agreement with the cross sections of fission of rhenium, tantalum, and holmium by 450-Mev protons. (R.V.J.)
