Оказывается, генератор событий для рассеяния Баба называется BABAYAGA !!!

Пруф, например, тут, и можно идти по ссылкам:)) Причем, среди авторов, похоже, ни одного русского:)) Как!?!?!..

Update 21.06.2021: внес этот факт в готовящееся издание КЭД в твердой обложке:))

The Gamma Factory (GF) is an ambitious proposal, currently explored within the CERN Physics Beyond Colliders program, for a source of photons with energies up to ≈400MeV and photon fluxes (up to ≈1017 photons per second) exceeding those of the currently available gamma sources by orders of magnitude. The high-energy (secondary) photons are produced via resonant scattering of the primary laser photons by highly relativistic partially-stripped ions circulating in the accelerator. The secondary photons are emitted in a narrow cone and the energy of the beam can be monochromatized, eventually down to the ≈1 ppm level, via collimation, at the expense of the photon flux. This paper surveys the new opportunities that may be afforded by the GF in nuclear physics and related fields.
