Abstract: The critical temperature shift $\partial T_c / \partial x$ of the spin-Peierls transition in quasi-one-dimensional material $\mathrm{Cu_{1-x} Zn_x GeO_3}$ were calculated for $x \ll 1$. The comparison with experiment was done.

Keywords: spin-Peierls transition, antiferromagnetic chain, Jordan-Wigner transformation.
