摘要：
The results obtained by experimentally and theoretically studying the yield of the promising nuclear-fusion reaction B-11(p, 3 alpha) initiated by powerful picosecond laser radiation of intensity 3 x 10(18) W/cm(2) are presented. A new procedure that relies on a simultaneous detection of the yield of alpha particles and the neutron yield in the reference reaction B-11(p, n)C-11 and which permits reaching a high precision of measurements is employed. The measured alpha-particle yield per pulse in the reaction B-11(p, 3 alpha) is 10(9) particles in 4 pi sr at the above laser-pulse parameters. The results of a numerical particle-in-cell (PIC) simulation of the nuclear-fusion reaction B-11(p, 3 alpha) proceeding in a solid-state boron target are presented. These results on the alpha-particle yield per pulse in the reaction B-11(p, 3 alpha) agree fairly well with experimental results.
