US–Soviet collaboration to measure pion charge radius

This month four UCLA physicists hope to arrive at the High‐Energy Physics Institute in Serpukhov to participate in the first joint experiment between Soviet and US physicists there. Darrell Drickey will head the US group and Edouard N. Tsyganov heads a group from Dubna. The collaboration will attempt to measure the charge radius of the pion by bombarding electrons with negative pions.
