We present the \nuk{Al}{26} and \nuk{Fe}{60} yields produced by a generationof solar metallicity stars ranging in mass between 11 and 120\msun. We discussthe production sites of these $\gamma$ ray emitters and quantify the relativecontributions of the various components. More specifically we provide theseparate contribution of the wind, the C convective shell and the explosiveNe/C burning to the total \nuk{Al}{26} yield per each stellar model in ourgrid. We provide the contributions of the He convective shell, the C convectiveshell and the explosive Ne/C burning to the \nuk{Fe}{60} yield as well. Fromthese computations we conclude that, at variance with current beliefs,\nuk{Al}{26} is mainly produced by the explosive C/Ne burning over most of themass interval presently analyzed while \nuk{Fe}{60} is mainly produced by the Cconvective shell and the He convective shell.Comment: 63 pages, 17 figures, 5 tables, ApJ accepte
