520 _ _ |a The gravitino regeneration rate $\Gamma_{\overline{G}}$ is calculated perturbatively to the leading logarithmic and corresponding constant order in the strong coupling constant g. Two approaches of obtaining the coefficient of the leading logarithmic term, one starting from individual gravitino production processes and one applying the thermal version of the optical theorem, are shown to deliver analytically the same result. In the second approach the next-to-leading constant term is obtained along with that coefficient. Here the imaginary part of the gravitino self energy is calculated in the framework of hard thermal loop effective field theory, with a resummed gluon propagator for both soft and hard gluons. The constant is strongly depending on the gravitino energy E. As an application, the implications of a large baryogenesis temperature, $T_B$ = 0($10^{10}$ GeV), on the mass spectrum of superparticles have been re-analyzed with the new value for $\Gamma_{\overline{G}}$. Previous phenomenological conclusions remain essentially unchanged.
