Abstract
Experimentally measured Gamow-Teller (GT) strength is generally less than that expected from models thought to be appropriate. This observation applies to transitions between single, defined energy levels as well as to entire GT strength functions. Over the past thirty years the scope of measurements and the nature of the interest in the problem have changed. However, the discrepancy persists and it signifies a fundamental difficulty in nuclear models. Various corrections have been proposed for the shell model such as high order configuration mixing and intrinsic excitations of the nucleons. A fully adequate model of GT transitions does not yet exist.
