Abstract : To check the predictions of a Universal Fermi Interaction, negative muons were brought to rest in a 1-1/2 inch filament scintillator chamber and the rate for the reaction - + C12 B12 + was measured. Ninety-seven B12 events were observed, giving a capture rate of (6.6 ! .9) x 103 per second. This number is in agreement with the predictions of a Universal Fermi Interaction, a pion induced pseudoscalar term with gP = + 8 gA, and a conserved weak vector current. An extensive discussion of the construction and operation of the filament chamber and associated image tubes is included. (Author)
