E meson observation in pi /sup -/p interactions at 395 GeV/c

Evidence for the E meson production in the reactions pi /sup -/p to K /sup 0/K/sup +or-/ pi n ( sigma =(8.2+or-1.0) mu b) is presented. The mass and width of the meson are M=(1426+or-6) MeV and Gamma =40+or-15 MeV. Analysis shows that the quantum numbers are, most likely, I/sup G /J/sup P/=0/sup +/1...

The mass and width of the meson are M=(1426+or-6) MeV and Gamma =40+or-15 MeV. Analysis shows that the quantum numbers are, most likely, I/sup G /J/sup P/=0/sup +/1/sup +/. The favoured decay mode is E to K/sup * /K+c.c. (7 refs).
