respectively. The mchanism of (n, 22n) reaction on Be connOsts in the neutron
emission by the excited 2.43-yev Be9*nucleus foming after inelastic neutrort
scattering. The latter is due to the fact that the reaction does not progi-Iiss in
the range of 1.8 - 2.7 Mev, where it is possible from the energy conditions, but
its cross section grows rapidly, starting from energy En -'2.70 Wv, above'Aich
the excitation of the 2.43-Mov level Is possible.

TEXT: The cross sections of the readtion,30(n,2n) IBe8wore measured in
dependence on the energy of the bombarding neutrons~' . The neutron's 'ource
was a deuterium gas target irradiated by electrostatically, accelerated I
deuterons. The proportional gas counters (BF,) were arranged in threes
concentric rings of 9, 18 and 27 counters (Fig. 1).~ The~,pulses from the
counters were recorded by radio with a coincidence, time tenolutionlof

efficiency of the detector was 5-5, 4.5 and 4.4 forLaeutrons of 3.7,' 4.1
