Weak decays and charm searches. Annual progress report, March 1, 1980-February 28, 1981

Results of statistically precise measurements of K/sup -/p and anti pp scattering cross sections, discussed in Annual Progress Report COO-4831-2, dated October 1979, were published in Physical Review and Physical Review Letters. Progress has been made in solving technical problems in a Brookhaven experiment in collaboration with experimenters from Yale and Brookhaven to measure the asymmetry parameter in the radiative decay ..sigma../sup +/ ..-->.. p..gamma... An experiment has been designed in collaboration with experimenters from the Lawrence Berkeley Laboratory and Brookhaven to search for the charmed eta and eta' mesons.
