%'e report high resolution measurements of inelastic electron scattering to all narrow normalparity states of '60 up to 12.05 MeV, which include states with J"(E"MeV): 0~+(6.049),The measurements were performed primarily at 90' and 160' and span momentum transfers between 0.6 and 2.6 fm '. Improved line shape fitting techniques have been developed. These are the first electron scattering measurements for the 4~+ state and of second form-factor maxima for several states. The form factor for excitation of the 2+2 state is strikingly different from that of the other 2+ states and indicates a transition density peaked in the interior. Transition charge densities were extracted from a combined data set that includes earlier electron scattering data renormalized to a recent analysis of elastic scattering from ' O. Comparisons have been made with several structure models, including the Brown-Green model, the weak-coupling model, a Pun shell model, and the tetrahedral alpha-cluster model.
High-statistics differential cross sections and spin-density matrix elements for the reaction γp → pω have been measured using the CEBAF large acceptance spectrometer (CLAS) at Jefferson Lab for center-of-mass (c.m.) energies from threshold up to 2.84 GeV. Results are reported in 112 10-MeV wide c.m. energy bins, each subdivided into cos θ ω c.m. bins of width 0.1. These are the most precise and extensive ω photoproduction measurements to date. A number of prominent structures are clearly present in the data. Many of these have not previously been observed due to limited statistics in earlier measurements.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
