High momentum transferRT,Linclusive response functions forHe3,4

Abstract
Inclusive electron scattering cross sections for He3,4 have been measured in the quasielastic region at electron energies between 0.9 and 4.3 GeV, and scattering angles of 15° and 85°. Longitudinal (RL) and transverse (RT) response functions have been extracted using a Rosenbluth separation at constant ‖q‖ of 1.050 GeV/c. The ratio of the longitudinal to the transverse reduced response functions in the negative y region reaches unity.
