A study of radiative decays of the neutral K mesons yielded the following limits with 90 confidence RKs to 2 gamma raysRKs to all1.2, RKL to pos. pion neg. pion gammaRKL to all 0.0056, and RKL to neut. pion 2 gammasRKL to all 0.00023. The branching ratio RKL to 2 gammasRKL to all is found to be 5.0 plus or minus 0.6 x 10-4, based on 115 events observed with negligible background. Author
