Abstract (data abstract)
DESY-PETRA.TASSO COLLABORATION. OBSERVATION OF THE EXCLUSIVE PRODUCTION OF K+K- AND K0SK0S PAIRS AND THE EXCITATION OF THE FPRIME (1515) TENSOR MESON IN PHOTON-PHOTON COLLISIONS. THE WIDTH (FPRIME--& gt;GAMMA GAMMA)*BR(FPRIME--& gt;K AK) ASSUMING A HELICITY STATE OF 2 IS FOUND TO BE 0.11 +- 0.02 (DSYS=0.04) KEV.
