Abstract

The muonic helium atom, αμ-e-, has been formed by stopping polarized negative muons in He gas at 14 atm with a Xe admixture of 2%, and observed through its characteristic Larmor precession frequency of 1.4 MHz/G. In addition a nonzero residual polarization of P=0.06±0.01 for μ- stopped in pure He gas has been measured for the first time, which corresponds to a depolarization factor of 18±3.
