The frascati microtron as synchrotron injector

Deuteron photodisintegration, quark-gluon string model, and Regge phenomenology

“…[14]: The total cross-section data for the reaction pp~r r+d [16] are described very well by the Regge model with the exception of the near threshold region. The available data on the reaction pd~m p (taken near the threshold [17] and calculated at v s =3.2 GeV from the data on the time-reversed reaction m. p -+pd [18]) agree also with the Regge model even near the threshold. These results encouraged us to use the quarkgluon model for deuteron photodisintegration starting from E& =400 MeV.…”

“…(2) where P, is the photon momentum in the center-ofmass system, T(s, t) and T(s, u) are the photodisintegration amplitudes, and R is the forward-to-backward ratio of the cross-section values. The energy behavior of T(s, t) for fixed t, which corresponds to the fermion Regge-pole exchange, can be written as [5,6] ' a~(t)~~1 [16] and pd~vr p, [17,18] as a function of c.m. energy, and the predictions of the QCJS model [14].…”

Exotic two-body final states in $$\bar p$$ annihilation on light nucleiannihilation on light nuclei

“…The first experimental evidence of the prototype Pontecorvo reaction was found by Bizzarri et al in bubble chamber events [3]. Six events of p annihilation at rest in LD 2…”

“…For this reason reactions like pd ! MB M = meson; B = baryon (3) are called unusual annihilations or exotic annihilations. np (2) and in general pd !…”

Numerical simulation of electrons dynamics in a microtron on 6 – 10 MeV

“…It can be an effective source of high energy photon radiation in photon and neutron activation analysis. Microtrons can be used for photonuclear reaction production [5], as well as for neutron production for pulsed fast neutron reactor [6]. The 6.5 MeV LPI microtron is used to study bremsstrahlung characteristics of relativistic electrons in complex structures.…”
