Study of the nuclear fusion in dμ3He complex

Experimental study of the nuclear fusion reaction in charge-asymmetrical dμ3He complex (dμ3He → α (3.5 MeV) + p (14.64 MeV) is presented. The 14.64-MeV protons were detected by three pairs of Si(dE - E) telescopes placed around the cryogenic target filled with the D2 + 3He gas at 34 K. The 6.85 keV γ rays emitted during the de-excitation of the dμ3He complex were detected by a germanium detector. The measurements were performed at two D2 + 3He target densities, ψ = 0.0585 and ψ 0.169 (relative to liquid hydrogen density) with an atomic concentration of 3He c3He = 0.0469. The values of the effective rate of nuclear fusion in dμ3He was obtained for the first time: λf(tilde) (4.5-2.0+2.6) · 105s-1(ψ = 0.0585); λf(tilde) = (6.9-3.03.6) · 105s-1(ψ 0.168). The J =0 nuclear fusion rate in dμ3He was derived: λfJ=0 (9.7-2.6+5.7) · 105s-1 (ψ 0.0585); λfJ=0 = (12.4-5.4+6.5) · 105s-1 (ψ 0.168)
