C. Thibault et al., MEASUREMENT OF THE ANTIPROTON INERTIAL MASS USING A RADIOFREQUENCY MASS-SPECTROMETER - PRESENT STATUS, Nuclear physics. A, 558, 1993, pp. 30000691-30000700
In order to test CPT invariance theorem, PS189 aims at checking the eq
uality of proton and antiproton masses via the measurement of the rati
o of H - and pBAR masses using a radio-frequency mass spectrometer. Re
cent progress, including a resolving power of 6 x 10(5), is presented.
