摘要：
The decays K+ --> e+ pi-0-pi-0-nu-gamma and K+ --> e+ pi-0-pi-0-pi-0-nu have been sought in photographs of 1.861.10(6) K+ decays recorded in a 180-liter xenon bubble chamber. No events corresponding to either of these decays were found. The following limits have accordingly been obtained on the probabilities for these decays at 90% C. L.: GAMMA(K+ --> e+ pi-0-pi-0-nu-gamma, E-gamma > 10 MeV)/GAMMA(K+ --> everything) < 5.10(-6), GAMMA(K+ --> e+ pi-0-pi-0-pi-0-nu)/GAMMA(K+ --> everything) < 9.10(-6).
