摘要：

Several series of shallow large-size (l much greater than lattice spacing) two-hole bound states are found in the two-dimensional t-J model. Their binding energies depend exponentially on the inverse value of the hole-spin-wave coupling constant. Their parity is connected with the angular wave function in a non-standard way. The possible role of these states in the formation of superconducting pairing is considered.
