Résumé : We try to check Adler's β sum rule for q2 = μ2. The integral of β can be divided into two parts: a first part which, if q2 = μ2, involves only an integral of the experimental πN cross section, and a second one which is a priori of order μ2 compared to the first. This second term can be approximated by an explicit calculation of the N 3 2 3 2* contribution in the framework of Adler's model for the νN → μN* reactions. The sum rule is not too well balanced and different hypotheses are presented to explain the defect. © 1973.
