We propose a special experiment for direct measurement of polarized gl
uon distributions in the collision of real high-energy photons with po
larized nuclear target. A polarized photon beam is obtained through Co
mpton back-scattering of laser photons off electrons from a ring-type
accelerator (LEP, TRISTAN, HERA). In our opinion, the realization of t
his experiment will play a principal role in solving the so-called <<s
pin crisis>>.
