Description

Complete sets of polarization transfer coefficients have been measured for quasifree (rvec p,rvec n) scattering from 2H, 12C, and 40Ca at 494 MeV and scattering angles of 12.5 degree, 18 degree, and 27 degree (q=1.2,1.7,2.5 fm-1). These measurements yield separated transverse (σ at sign x/Iq) and longitudinal (σ at sign ·/Iq) isovector spin responses. Comparison of the separated responses to calculations and to electron-scattering responses reveals a strong enhancement in the spin transverse channel. This excess transverse strength masks the effect of pionic correlations in the response ratio
