The nuclear spin-isospin response to quasifree nucleon scattering
- Los Alamos National Laboratory, Los Alamos, New Mexico 87545 (United States)
The Neutron-Time-of-Flight (NTOF) facility at LAMPF has been used to measure complete sets of polarization-transfer coefficients for quasifree ({ital {rvec p}},{ital {rvec n}}) scattering from {sup 2}H, {sup 12}C, and {sup 40}Ca at 494 MeV and scattering angles of 12.5{degree}, 18{degree}, and 27{degree} ({ital q}=1.2, 1.7, 2.5 fm{sup {minus}1}). These measurements yield separated transverse ({sigma}{times}{bold q}) and longitudinal ({sigma}{center_dot}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.
