摘要：

A search for mu --> e conversion in muonic atoms is being performed at PSI with the SINDRUM II spectrometer. A first measurement on Ti gives upper limits on the branching ratios for the ground-state transitions of GAMMA(mu-Ti --> e-Ti(g.s.)/GAMMA(mu-Ti capture) < 4.3x 10(-12) and GAMMA(mu-Ti --> e+Ca(g.s.)/GAMMA(mu-Ti capture) < 4.3x 10(-12) (90% confidence). With the assumption of a giant resonance excitation of the Ca nucleus the limit on the total rate for mu- --> e+ conversion is GAMMA(mu-Ti --> e+Ca*)/GAMMA(mu-Ti capture) < 8.9 x 10(-11).
