| Title | Extraction and Parametrization of Isobaric Trinucleon Elastic Cross Sections and Form Factors | ||||
| Abstract | By mining data from Je¿erson Lab Hall A experiment E08-014 a new 3He elastic cross section was extracted from a large quasielastic background. This measurement was taken with an initial beam energy of 3.356 GeV and an angle of 20.51¿. The cross section was found to be 1.345 × 10-6 µb/sr ± 0.086 × 10-6 µb/sr at Q2 = 34.19 fm-2. This new data point falls approximately halfway between the ¿rst and second di¿ractive minima of the 3He form factors. When combined with recent high Q2 3He elastic cross section measurements from Je¿erson Lab and MIT-Bates this new data point improves our knowledge of the cross section and form factors at large momentum transfers. The new high Q2 data motivate a reanalysis of the 3He elastic cross section world data and provide an improved understanding of the magnetic form factor in particular. For this analysis the elastic cross section world data for 3He, and its mirror nuclei 3H, were collected. The world data spans a time frame from 1965 to 2016. The datas | ||||
