- Abstract
The results of experimental investigations devoted to initiating the promising nuclear fusion reaction B in picosecond laser plasmas at a laser-radiation intensity of W/cm are presented. A new tool for determining the absolute yield of alpha particles in the reaction B on the basis of simultaneously measuring the number of neutrons in the reference nuclear reaction B C is proposed. At the above values of the laser-pulse parameters, the application of this new procedure to estimating the total number of alpha particles per pulse from the reaction B leads to a value of 10 particles within a solid angle of 4 sr. The results presented here differ substantially from the data obtained in measuring the single-channel yield of alpha particles.
