The yield of {alpha} particles in neutronless fusion reactions {sup 11}B+p in plasmas produced by picosecond laser pulses with the peak intensity of 2x10{sup 18} W/cm{sup 2} 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 {sup 11}B+(CH{sub 2}){sub n} were used. The yield of 10{sup 3} {alpha} particles per pulse has been observed. The energy spectrum of {alpha} particles contains two maxima: at 3-4 MeV and at 6-10 MeV. The first of these peaks corresponds to the secondary {alpha}{sub 12} particles at the decay of the intermediate first excited state of {sup 8}Be, whereas the second peak demonstrates generation of {alpha}{sub 1} particles in the reaction {sup 11}B+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.
