The cross section for production of Fm/sup 250/ in the reaction Pu/sup 241/(Csup 13/,4n) and U/sup 238/(O/sup 16/,4n) was determined as a func tion of the energy of the bombarding particles. Comparison of the cross section for production of Fm/sub 250/ with the fission cross section in these reactions shows that in the overwhelming majority of cases the excited compound Fm/sup 254/ nucleus undergoes fission, and only in a very few cases deexcitation takes place as a result of neutron emission. The maximal cross section for production of Fm/ sup 250/ by irradiation with oxygen or carbon ions is, respectively, 1 x 10/sup - 30/ cm/sup 2/ and 5 x 10/sup -30/ cm/sup 2/. The difference betwee n the cross sections is probably due to the effect of the Coulomb barrier. (auth)
