Méthode GPT. Au milieu des années 1960, Usachev, Lewins et Gandini généralisèrent la théorie des perturbations à toute sorte d’observable, paramètre physique pouvant être mesuré (et/ou calculé), qui peut être représenté sous la forme d’un rapport de quantités intégrales, linéaires du flux et/ou du flux adjoint. Pour reconstruire la valeur d’un observable d’un système multiplicateur dans des conditions perturbées, la théorie généralisée des perturbations […] fait appel à une fonction particulière, dite fonction importance généralisée, qui est la solution unique de l’équation du bilan adjointe du système à laquelle on ajoute un terme inhomogène, appelé source généralisée. Ce terme, qui est strictement orthogonal au mode fondamental, contient, au premier ordre, l’information sur la nature de la perturbation et son impact sur le flux. 1, record 5, French, - source%20g%C3%A9n%C3%A9ralis%C3%A9e
