Abstract : The double Gamma emission was studied in the monopole transitions of energy 6.06 MeV in 16O, 3.35 MeV in 40Ca and 1.73 MeV in 90Zr, obtained from the reactions 19F (p Alpha) 16O and 40Ca (pp') 40Ca, and by Beta(-) radioactivity ofA 90Sr source, respectively. In the case of 16O, the value T(Gamma Gamma) over T sub tot equals (2.5 ! 1.1) x 1/1000 is found. For 40Ca and 90Zr upper limits of 2.4 x 1/1000 and 1/4 x 1/1000 respectively were obtained. Comparisons with theoretical predictions and other experimental values are given. (Author)
