We have analyzed hadronic B decays into psiK, Dpi, Dpi, and Drho chan
nels with a view to investigate if the uncertainties in the form facto
rs and inclusion of final state interactions and annihilation terms wo
uld allow solutions with negative a2/a1. We have concluded that the ne
w CLEO II data cannot be understood with negative a2/a1 even after all
owing for the effects mentioned above.
