FIRST MEASUREMENT OF THE TENSOR ANALYZING POWER T-20 IN INELASTIC (D,D')X SCATTERING AT O-DEGREES ON H-1 AND C-12 AT 4.5 AND 5.5 GEV/C

First results for T-20 of the inelastic (d,d')X reaction above the Delta threshold are presented. It is observed that T-20 is negative; its absolute value is small in the Delta region and rises almost linearly to \T-20\ similar or equal to (0.4-0.6) at energy transfers Q similar or equal to 1 GeV. No significant dependence on the type of the target and on the initial energy was observed.
