Abstract
In this study a complete set of exclusive (~p; 2p) polarization transfer observables of closed-shell oxygen
isotopes are calculated using both direct and inverse kinematics using the relativistic plane wave impulse
approximation. The interaction matrix is written in terms of the SPVAT (scalar, pseudoscalar,
vector axial vector, tensor) covariants where each amplitude is obtained directly from experimental
phase shifts. A relativistic mean eld theory approximation is used to compute boundstate wave
functions of the nucleons. We study the evolution of polarization transfer observables within oxygen
isotopes and identify observables which may discriminate between these isotopes. The same kinematical
conditions are considered for both direct and inverse kinematics: the incident energy is set
at 504 MeV and coplanar angles are xed at (22:12 ;40:30 ). The results indicate that only three
spin observables, namely, Ay, P and Dnn distinguish di erent oxygen isotopes at these kinematical
conditions in the inverse kinematics.
