摘要：

Complete sets of polarization transfer coefficients have been measured for quasifree (p→,n→) scattering from H2, C12, and Ca40 at 494 MeV and scattering angles of 12.5°, 18°, and 27°(q=1.2,1.7,2.5 fm-1). These measurements yield separated transverse (σ×q) and longitudinal (σ•q) 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. © 1994 The American Physical Society.
