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 (...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | 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 (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. |
