摘要：
The angular correlation of gamma-quanta emitted in the capture of stopped π- mesons in hydrogen is measured. The measurements were performed by using scintillation and gas-discharge counter hodoscopes. The value of the mass differences between charged and neutral π mesons was found to be 4.6034±0.0052 MeV/c2. An upper probability limit for the production of a second neutral π meson, which has the mass in the range of 135 - 138 MeV/c2 has been determined. © 1969.
