Description
A large fraction of the number of positrons observed in collisions of 238U + 238U, 238U + 208Pb, and 208Pb + 208Pb at relative velocities ν/c = 0.11 and for distance of closest approach R/sub m/ in < 40 fm can be assigned to pair creation of nonnuclear origin, induced by the time-varying Coulomb fields of the projectile and target charges. An order-of-magnitude increase in the positron yield is observed by increasing the united-atom charge from 164 to 184
