  Predictions for some experimental physical observables in nucleus-nucleus
collisions at RHIC energies are presented. I utilize the previous suggestion
that the retarded, by time about 2-3 fm/c, jet absorption in opaque core is a
natural explanation of many experimental data. This assumption is applied only
to the particles with high transverse momentum above 4 GeV/c resulting from
parton fragmentation. I calculate nuclear modification factor $R_{AA}$,
$R_{AA}$ in- and out of the reaction plane, azimuthal anisotropy parameter
$v_2$, jet suppression $I_{AA}$ for the away side jet and its dependence versus
the reaction plane orientation. The systems under consideration are Au+Au,
Cu+Cu, at 200 GeV and 62 GeV. Most of numbers are predictions prior to the
QM2006.
