The identification of the isovector member of the scalar nonet plays a fundamental role in fixing the properties of the other members and, therefore, in the possible identification of an extra state as the glueball candidate. After more than 20 years of experiments on this subject the situation has not yet been clarified. A review of the experimental results coming both from annihilation and the reaction is presented in this paper.
