Artamonov, A.S. et al.
A High Precision Measurement of the (1S), (2S) and (3S) Meson Masses
Phys. Lett. 137B (1984) 272; NOVO-83-84 (1983);

An experiment has been performed at the storage ring VEPP-4 using MD-1 detector. The resonance depolarization method has been employed for the absolute calibration of the beam energy. This has allowed the accuracy of the mass measurement to be improved by a factor of ten. The following mass values of (1S), (2S) and (3S) mesons have been obtained: M((1S)) = 9460.0 0.4 MeV, M((2S)) = 10023.8 0.5 MeV, M((3S)) = 10355.5 0.5 MeV.
