Description
The measurement of cross-section for the nuclear fusion reaction $d+^3He{\to}^4He+p$ at ultra-low energies is of interest in pure and applied physics. This fusion process is involved in the primordial nucleo-synthesis of the light elements in the early Universe. This reaction is a mirror reaction of the $d+t{\to}^4He+n$ fusion process and can be considered as a perspective source of thermonuclear energy.
We present a detailed study of the search for muon catalyzed $d^3He$-fusion, which was performed using the MuSun experimental setup. Based on the collected statistics , an upper limit for the rate ${\lambda_f}$ of muon catalyzed $d^3He$ fusion was set in this experiment performed with the $D_2+^3He(5{\%})$ gas mixture at $31K$ temperature with the gas density ${\phi}=6.2{\%}$ of the LHD ${\lambda}_f{\le}6.3{\cdot}10^4s^{-1}~at~90{\%}~C.L.$
