Status Report on Experiment PS172: p̄p Total Cross: Section and Spin Effects in p̄p + K+K-, π+π- and p̄p

In the beginning of 1980 four letters of intent for experiments at LEAR had been submitted which all proposed to study either pp total cross section or spin effects in pp (elastic) scattering or both. The people who wrote these letters were asked to work together and to submit one proposal covering all the experiments mentioned in the original letter of intent. The proposal resulting from this effort suggests to do a wide range of experiments using a rather complicated set up.
