本文提出了一种简便的表示方法（§ 2），用于τ介子衰变组态的数据，适用于不区分不同的出射π介子的情况。在一些简单情况下，得到了τ介子的自旋和宇称与衰变组态分布的关系。τ介子和X介子相同的假设要求这种粒子的自旋不为零，而关于τ介子衰变的现有数据并不排除这种可能性。然而，如果不区分不同的出射π介子，则在区分各种可能性时相对无效。本文讨论了强介子-介子吸引在τ衰变组态中可能产生的畸变，目前的数据没有提供这种效应的证据。
Abstract A convenient method of representation is proposed (§ 2) for data on τ-meson decay configurations, applicable when the unlike outgoing π-meson is not distinguished. The relation between the spin and parity of the τ-meson and the distribution of decay configurations is obtained for some simple cases. The hypothesis that the τ- and X-mesons are identical requires a non-zero spin for this particle and the available data on τ-meson decay does not exclude this possibility. However, observations in which the unlike outgoing π-meson is not distinguished are relatively ineffective in discriminating between the various possibilities. The distortions which strong meson-meson attraction may produce in τ-decay configurations are discussed ; the present data offers no evidence on this effect.
