چکیده
Results on the two-photon production of the n', f(1270), A2(1310), and f'(1515) mesons at SPEAR energies are presented using data taken with the Mark II detector. The radiative width of the n' has been determined to be pYY(n') = 5.8 +_ 1.1 keV (20% systematic uncertainty). Upper limits for the radiative widths of the f, A2, and f' have been determined. R&sum&: Nous presentons des resultats sur la production de n', f(1270), A2(1310) et f'(1515) aux energies de SPEAR par le proces de 2-f dans le detecteur Mark II. La largeur radiative de n' est determinge comme pw(n') = 5.8 ?r 1.1 keV (20% d&reurs systematiques). Des limites superieurs aux largeurs radiatives ont et& determinees pour les mesons f, A2 et f'., (Presented at the XVth Rencontre de Moriond: Electroweak Interactions and Unified Theory Predictions, Les Arcs, France, March 15-21, 1980.) * Work supported by the Department of Energy under contract DE-AC03-76SFO0515.

Exclusive Final States from Photon - Photon Collisions at Spear
Studies of exclusive final states produced by the two-photon process have been made at SPEAR by the Mark II and by the Crystal Ball Collaborations. region 500 MeV/c2 Measurements of r%rand x0x0 production in the mass < mx, < 2000 MeV/c2 are presented. These data include strong signals from the well-known f(1270) meson. The A2(1310) has been observed via its rr"n decay mode and its partial width...
متن کاملSPEAR III A Brighter Source at SSRL
By replacing the magnets and vacuum chamber for the 3 GeV SPEAR II storage ring, the natural emittance of the machine can be reduced from 130 to 18 nm-rad and the stored current can be raised from 100 to 200 mA with a 50 h lifetime. This configuration increases focused photon flux for insertion device beamlines by an order of magnitude and the photon brightness for future undulators would excee...

The Mark II experiment first started taking data in 1978 at the SLAC SPEAR storage ring. It was the first e+edetector with a large, many layer cylindrical drift chamber (CDC) and a large liquid argon calorimeter!” After two years at SPEAR, it was moved to the PEP storage ring, where it was upgraded a year later with a seven layer precision vertex drift chamber!’ located between the CDC and the ...

The Potential Energy Surface PES of (H2)2 dimer has been investigated, using five simple rigid rotor models. These models are called: head to head, symmetric side to side, L , steplike and T model. All calculations were done at two levels of ab initio methods: MP2(Full) and QCISD (T,Full) using cc-pVTZ basis set at singlet state of spin multiplicity. The results of scanning PES were then fitte...
