Photoexcitation of ⁸⁷mSr by (γ,γ') reaction
The photoexcitation of ⁸⁷mSr (energy of isomeric level Eiso = 388.532 keV ) using the gamma rays produced by electron electrostatic accelerator was examined for the bremsstrahlung end-points energy covered the range from 1.4 to 3.1 MeV . Isomer activation yield was measured and intermediate states (...

Isomer activation yield was measured and intermediate states (IS) 1228, 1770, 1920 and 2656 keV contribution were observed. Experimental and published nuclear Resonance Fluorescence data were analyzed and photo-activation intermediate state integral cross section determined, which are: 0.090, 0.009, 0.070 and (1.7 ± 0.5) eV · b. |
