Recombination of H-3(+) with electrons is studied in a low-temperature plasma containing He, H-2 and Ar at different He and H-2 densities. The effective plasma recombination rate is driven by binary, H-3(+) + e(-), and ternary, H-3(+) + e(-) + He, processes with the rate coefficients 7.5 x 10(-8) cm(3) s(-1) and 2.8 x 10(-25) cm(6) s(-1) respectively at 260 K. We suggest that the ternary recombination involves formation of neutral highly excited Rydberg H-3 followed by an l-changing collision with He. The difference between recombination of para- and ortho-H-3(+) is discussed.
