Measurement of the excitation function for the 7Li(t, p)9Li reaction using detection of delayed neutrons

The excitation function for the 7Li(t, p)9Li reaction is measured at the EGP-10 electrostatic tandem accelerator (VNIIEF) at the incident triton energies Et= 5–11.3 MeV. The measurements were based on detection of delayed neutrons resulting from the decay of 9Li nuclei. The neutrons were detected by the 4π detector consisting of 3He counters enclosed in a polyethylene moderator. A pulsed mode was used for irradiating the LiF target (210 μg cm−2) of natural isotopic composition on the tantalum backing. Absolutization of the excitation function was performed against the 7Li(p, n) reaction cross sections.
