PRECISE MEASUREMENTS OF THE MEAN LIVES OF $mu$$sup +$ AND $mu$$sup -$ MESONS IN CARBON (thesis)

Technical Report ·
OSTI ID:4057061
The lifetimes of approx 6 million positive mu mesons were measured, using a crystal controlled oscillator as a clock. The resulting decay curve was analyzed on a digital computer and gave a mean life of 2.211 plus or minus 0.003 mu sec. The mean life of negative mu mesons in carbon was measured and found to be2.043 plus or minus 0.003 mu sec. The resulting nuclear capture rate is (0.373 plus or minus 0.011) x 10/sup 5//sec, assuming that the decay rate of a negative mu meson bound in carbon is equal to the decay rate of the positive mu meson.
