Cross section (σ), analyzing power (${\mathrm{A}}_{\mathrm{y}}$), induced polarization (P), and normal polarization transfer ${\mathrm{coefficientD}}_{\mathrm{N}{\mathrm{N}}^{\prime }}$) data have been measured for scattering of 200-MeV polarized protons from ${\mathrm{B}}^{10}$. Data for the $3^{+}$, T=0 to $0^{+}$, T=1 (1.74 MeV) isovector 0ħω stretched transition are compared to results of distorted-wave calculations. While σ, ${\mathrm{A}}_{\mathrm{y}}$, and P are reasonably described by calculations based on the free nucleon-nucleon(NN)t matrix, the ${\mathrm{D}}_{\mathrm{N}{\mathrm{N}}^{\prime }}$ data are not. The results suggest a larger transverse to longitudinal spin-dependent interaction ratio than is expected from free NN scattering. © 1992 The American Physical Society
