Electroproduction of K+Lambda at JLab Hall-C
A Lambda hypernuclear spectroscopic experiment, JLab E05-115 was performed at JLab Hall-C in 2009 by the (e, e′K+) reaction. Data of Lamnda hypernuclei with mass numbers from A=7 to A=52 were successfully taken, and the analyses are in progress. A polyethylene (CH2) target was used as a proton target to calibrate energy scales, and to study elementary process of the p(e, e′K+)Lambda, Sigma0 reaction. A preliminary differential cross section of K+Λ electro-production at low Q2 (~ 0.01 (GeV/c)2) and at small kaon angles at the CM system (cos thetaK ~ 0.97) is reported in the present article.
