The tensor analyzing power T{sub 20} and the spin transfer coefficient {kappa}{sub 0} for the deuteron breakup reaction {sup 1}H(d, p)X at 0{degrees} and at high energy are functions of the D/S ratio of the deuteron wave function (DWF) and are related by the equation of a circle in the {kappa}{sub 0}-T{sub 20} plane if (1) the deuteron wave function has the commonly accepted S- and D-component structures and (2) the mechanism of the breakup reaction does not change the spin of the detected proton. This correlation of the two polarization observables is independent of any model of the deuteron wave function with 2-component structure. The experimental data deviate from the {kappa}{sub 0}-T{sub 20} circle, indicating that at least one of the above assumptions is not fulfilled. Two assumptions are discussed to explain this deviation: (1) the DWF has additional components, for example the N{sup *}N P-wave and (2) complicated spin-dependent interfering graphs change the spin of the detected proton. We suggest an experimental way to verify the first of these assumptions by searching for the {eta} decay of the negative parity N{sup *}(1535) baryon of the N{sup *}N component in the deuteron ground state. 17 refs., 3 figs.
