Abstract
Using data from the Mark III detector at the e+e- storage ring at SPEAR, an upper limit of .30 at the 90% confidence level is set on the magnitude of the CP asymmetry Acp for the CP eigenstate no -+ K+ K-. This falls within the preexisting limit of .45 @90% CL set by FNAL experiment E691 using the same decay. The first measurement of Acp is made for two other CP eigenstates, no -+ K2 K2 and no -+ 1r+1r-. An upper limit for the branching ratio for the decay, no -+ K-?r+?r0 ?r0 ?r0 , for which evidence was found in the process of measuring Acp, is set at 12.1%.
