The problem of correlation between a trion and a hole in the electron Fermidistribution created in the process of trion photo-excitation in doped quantumwells is under consideration. The hole in the Fermi distribution appears in thetrion creation process consisting of picking of the Fermi Sea electron up bythe exciton created in virtual state due to photon absorption. It isdemonstrated that the interaction results in formation of a correlated state ofthe trion and the hole in the Fermi Sea. The state has excitation energy whichis less then trion energy minus Fermi energy that can be obtained as a loweredge of trion excitation band using the simple energy conservation low in thepicture of independent trion and electrons. The wave function of the correlatedstate is real and decreases with increase of distance between the trion and theFermi Sea hole, r, as 1/r^3/2. The wave function can be normalized to unity andit corresponds to correlated state of the trion and Fermi Sea hole. In contrastto this state, the states with excitation energies in the absorption bandbetween the trion energy and the trion energy minus Fermi energy have complexwave functions that decrease as 1/r^1/2. These states correspond to the trionand the Fermi Sea hole that is running away from the trion. The correlatedstate described above is supposed to be responsible for the narrow trionabsorption line that was observed experimentally.
