  We suggested a dimensionless relativistic invariant variable (R) which may be
interpreted as a ratio of the excitation energy to the full transferred energy;
therefore this variable measured a "degree of inelasticity" of the scattering.
Existing data on the tensor analysing power of p(d,d')X and 12C(d,d')X
inelastic scattering at momenta from 4.2 to 9 GeV/c are analysed in terms of
this variable. We observe that Ayy taken as function of R does not depend upon
the incident energy, the scattering angle (up to 30 deg. in CM frame); there is
no noticeable difference between the proton and carbon targets as well. It is
remarkable that Ayy is maximal when R near to 0.5-0.6 and small in absolute
value when R is close to its limiting values of 0 and 1.
