Abstract
The muon capture rate in the reaction mu(-)+He-3-->nu(mu)+H-3 has been measured at PSI using a modular high pressure ionization chamber. The rate corresponding to statistical hyperfine population of the mu(3)He atom is (1496.0+/-4.0)s(-1). This result confirms the PCAC prediction for the pseudoscalar form factors of the He-3-H-3 system and the nucl eon. (C) 1998 Elsevier Science B.V.
