The Dibarion resonance d(2380) was measured in the two pion production
reactons $pN->d\pi\pi$ and by use of a polarized
deuteron beam in the quasifree scattering mode on hydrogen target.
Total and differential cross sections have been measured for the various isotopic
final states. Covered energy region includes the regions of N
(1440) and
$\Delta(1230)\Delta(1230)$ resonance excitations. Calculations using t-channel
meson exchange differ from the experimental data. An isotensor
$\Delta$N Dibarion I($J^P$)=2($1^+$) state is able to compensate observed difference.
