Abstract
The yield of α particles in
neutronless fusion reactions 11B+p in plasmas produced by picosecond
laser pulses with the peak intensity of 2 × 1018 W/cm2 has
been observed. Experiments were carried out on the “Neodymium” laser facility at
the pulse energy of 10–12 J and pulse duration of 1.5 ps. The composite targets
11B+(CH2)n were used. The yield of 103
α particles per pulse has been observed. The energy spectrum of α
particles contains two maxima: at 3–4 MeV and at 6–10 MeV. The first of these
peaks corresponds to the secondary α12 particles at the decay
of the intermediate first excited state of 8Be, whereas the second
peak demonstrates generation of α1 particles in the reaction
11B+p with the production of this excited state. Simultaneous
measurements of neutrons result in zero yield, which proves the observation of
neutronless fusion reactions in our experiments.
