Electron decay of the positive pion

HL Anderson, T Fujii, RH Miller, L Tau - Physical Review Letters, 1959 - APS
The remarkable success of the AV theory'~'in accounting correctly for many related
phenomena had raised doubt aboutour failure to observe this process. Accordingly, we …

Lifetime of the Neutral Pion

G Harris, J Orear, S Taylor - Physical Review, 1957 - APS
A new upper limit on the π 0 lifetime has been obtained by using 12 K π 2+ endings in
nuclear emulsion where the π 0 decays by a direct pair, π 0→(e++ e−)+ γ. The distance …

Branching ratio of the electronic mode of positive pion decay

HL Anderson, T Fujii, RH Miller, L Tau - Physical Review, 1960 - APS
A new measurement of the branching ratio (π+→ e++ ν)(π+→ μ++ ν) has been completed. A
double-focussing magnetic spectrometer was used to observe the spectra of electrons …

[CITATION][C] The experimental clarification of the theory of beta-decay

EJ Konopinski, LM Langer - Annual review of nuclear science, 1953 - annualreviews.org
Fermi advanced his successful theory of p-decay in 1934. It has since then undergone
development in which two general directions may be dis cerned. One has been a …

Decay of the Pi Meson

SB Treiman, HW Wyld Jr - Physical Review, 1956 - APS
It is known experimentally that, relative to the normal pion decay mode π→ μ+ ν, the
branching ratios ρ and ρ γ for the alternate decay modes π→ e+ ν and π→ e+ ν+ γ are very …
