It is shown that the relaxation rates of the spin distribution function of two-dimensional electron gas are substantially different for even and odd angular harmonics. For even harmonics, the relaxation rate of the spin distribution function is equal to the relaxation rate of the density distribution function, demonstrating a logarithmic increase with the number of harmonic and\n                    <a:math xmlns:a=\"http:\/\/www.w3.org\/1998\/Math\/MathML\">\n                      <a:msup>\n                        <a:mi>T<\/a:mi>\n                        <a:mn>2<\/a:mn>\n                      <\/a:msup>\n                    <\/a:math>\n                    temperature dependence.
