ELECTRONIC CONDUCTIVITY OF MGO-DOPED NA-BETA-ALUMINA - A REEVALUATION

Due to a Raw in the evaluation of Hebb-Wagner polarization measurement s which were published some time ago the resulting p-electron conducti vity data are incorrect. As these data have so far been regarded impor tant from the viewpoint that in the low temperature range they might r epresent an alternative conductivity level significantly different fro m other results, the original measuring data are re-evaluated. Particu lar importance is attached to the question of how the suggestion of th e occurrence of two conductivity levels is affected. It turns out that the answer to this question depends on whether the experimental data are re-evaluated according to the Hebb-Wagner theory, i.e., convention ally, or, since the data do definitely not obey this theory, according to an advanced relationship.
