SummaryThe distribution of the π-mesons in the decay of the τ-meson is studied, and approximate expressions for the matrix elements are found. Thus one can justifyDalitz’ results, in which the relativistic corrections are also introduced. The comparison with experiment is done taking into account the charges of the π-mesons; the experimental data, however, are still too poor to give any information about parity and spin of the τ-meson.RiassuntoSi studia la distribuzione dei mesoni π nel… Expand
Remarks on the analysis of τ-meson experiments
SummaryThe results from the analysis of 75 stopped τ-meson decays, found in a stack of emulsions exposed to the Berkeley Bevatron, are discussed. Special attention is paid to the effects of theExpand
An analysis of 419 π-meson decays
SummaryA homogeneous sample of 419 π-decays found in nuclear emulsions exposed to the Berkeley Bevatron has been used in the present analysis. Special attention has been given to reducing the effectsExpand
On the spin and parity of the τ-meson
SummaryThe angular distributions of the secondaries of the τ-meson have been calculated for eight combinations of spin and parity, using the hypothesis accepted untill now about the type ofExpand
An analysis of the spin and parity of the τ-meson
SummaryThe generality of the double angular momentum expansion for the final state in T-meson decay (1) is pointed out. The significance of the relativistic corrections is emphasized. A relativisticExpand
On the spin of artificially produced τ-mesons
SummaryMeasurements have been carried out on theπ-meson secondaries arising from the decay of positive π-mesons recorded in a stack of nuclear emulsions which had been exposed to the positive K-mesonExpand
On the decay modes of interacting and non-interacting K+-mesons
SummaryThe decay modes of K+-mesons which have been inelastically scattered from nuclei in emulsion have been determined and. it is shown that their relative frequencies are consistent with thoseExpand
Some consequences of the decay modes and production of the new heavy bosons
SummaryAn investigation is made of the consequences following from the production and decay of the recently discovered heavy bosons. It is found that various correlation experiments can determineExpand
Erratum to: On the pion annihilation of nucleon-antiproton pairs
SummaryThe pion annihilation of antiproton-nucleon pairs in boundS-states (singlet and triplet) are analyzed taking into account conservation law and selection rules previously founded. With aExpand
Analysis of one hundred Bevatron τ+ particles
SummaryOne hundred τ+ mesons, obtained from nuclear emulsion stacks exposed to the K+ beam at the Bevatron, are analyzed for (a) Q-value of the τ-decay, (b) possible values of the spin-parity of theExpand
On theQ-value of the Tau-Decay
SummaryTheQ-value of the π-decay has been determined in photographic emulsions, by a procedure which, using the joint information given by ranges and angles of the secondary particles, excludes theExpand


Contributions to the Τ-meson investigation
SummaryTwo Τ-mesons have been observed in photographic emulsions exposed to cosmic rays at an altitude of 26 000 metres. The corresponding data are summarized in par.2. The process of decay ofExpand
CXII. On the analysis of τ-meson data and the nature of the τ-meson
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 theExpand
