Z dependence of the (γ, α) reaction yield
Reactions induced by photons may be used as a probe for bonds and correlations of nucleons inside a heavy target nucleus. In contrast to strongly interacting particles, electromagnetic radiation perturbs nucleons only slightly. The yield of ( γ , α ) reactions could be used to test theoretical model...

| description | Reactions induced by photons may be used as a probe for bonds and correlations of nucleons inside a heavy target nucleus. In contrast to strongly interacting particles, electromagnetic radiation perturbs nucleons only slightly. The yield of (
γ
,
α
) reactions could be used to test theoretical models that assume complete alpha-particle clustering or the presence of multiquark objects in heavy nuclei. The relative yields of (
γ
,
n
), (
γ
,
p
), and (
γ
,
α
) reactions were measured at the bremsstrahlung endpoint energy of 23 MeV for several targets. A much lower probability of (
γ
,
α
) in relation to (
γ
,
p
) reactions was proved despite very close threshold and spin factors for the two reaction types being considered. Therefore, alpha-particle clustering in heavy targets was not confirmed. The mechanism of particle release in nuclear reactions is discussed, and some details are clarified. |
