摘要：

The results of the spin-parity analysis of the annihilation reaction <(p)over bar p> --> pi(+)pi(-)pi(0) at rest are presented. For the first time data from liquid, NTP and low pressure hydrogen are fitted simultaneously. This technique allows to disentangle unambiguously the contributions of the different initial atomic states. The results concern the weights of the partial waves, masses and widths of the 0(++), 1(--) and 2(++) resonances produced in the annihilation.
