In this article we report the results of an experiment performed in 19
93 at PSI. The goal was to determine the absolute rate of nuclear muon
capture by He-3. In the experiment we used a new technique recently d
eveloped at Gatchina. As a preliminary result from this experiment we
obtained Lambda(C) = (1496 +/- 3 (stat) +/- 3 (syst)) s(-1).
