The analyzing power ${\mathit{T}}_{20}$ in the inclusive ${}_{}{}^1{}_{}{}^{}\mathrm{H}$${(}^6$Li,d or α or t)X reaction with 4.5 GeV tensor polarized ${}_{}{}^6{}_{}{}^{}\mathrm{Li}$ nuclei has been measured at an angle of 0.8°. The kinematics chosen favor the detection of spectator fragments; in the impulse approximation the laboratory momentum of such a fragment is then the Lorentz boosted internal momentum. Nonzero ${\mathit{T}}_{20}$ values have been observed, in agreement with the known nonsphericity of ${}_{}{}^6{}_{}{}^{}\mathrm{Li}$ indicated by its quadrupole moment. The sign of ${\mathit{T}}_{20}$ in the d channel suggests that near q=0 the D state in ${}_{}{}^6{}_{}{}^{}\mathrm{Li}$ has the same sign as in the deuteron; an abrupt change of sign near q=0.12 GeV/c is in agreement with theoretical expectation of a node in the αd position wave function. The α-channel data show larger ${\mathit{T}}_{20}$ values than the d channel; in this case the small-q-region has not been explored enough to establish a similar node. A few data points in the t channel might suggest that ${\mathit{T}}_{20}$ becomes positive above q=0.4 GeV/c in this case.
