“…Together with an increase in cross section originating from reciprocity arguments, one obtains an increase in luminosity that allows a measurement of cross sections in the pb region even with the modest beam intensities available at existing facilities. Next generation facilities [18,19,20] will have considerably higher intensities which might open the possibility to obtain experimental cross sections for capture reactions at astrophysical energies.…”

“…Background reactions such as 19 F(γ,p) 18 O or 12 C(γ,2α)α are energetically forbidden in the energy range E γ =5-6 MeV. Two-step processes like 13 C(γ,n) 12 C followed by elastic scattering of the resulting neutron are suppressed by the low abundance of 13 C and by the small cross sections of the (γ,n) reactions at energies close to the threshold (E γ =4.946 MeV).…”

Photo-excitation production of medically interesting isomers using intense γ-ray source

“…To induce efficiently the photo-excitation process, a high-brightness γ-ray beam is required, such as Bremsstrahlung beam [24] and LCS γ-ray beam [25]. The LCS γ-ray beam is produced by incoherent Compton back-scattering of laser light from brilliant high-energy electron bunches, in which the laser photons take substantial energy from electrons and then boost successfully into the higher X or γ-ray beam energy region.…”

Searching for Dark Matter Particles with Compton Scattering Approach

“…Shanghai laser electron gamma source (SLEGS) which is under construction is located at Shanghai Synchrotron Radiation Facility (SSRF), Shanghai, China [19][20][21]. It can produce a high intensity γ-ray beam by using laser Compton scattering (LCS) between 3.5 GeV electrons in the storage ring of SSRF and photons from a CO 2 laser.…”
