摘要: The inclusive partial photoneutron cross sections and the total section\(\sigma ^{(1)} (E_\gamma ) = \sum\limits_{i 1}^{i_{\max } {\sigma (\gamma ,in...)} \) for natural Zr have been measured from 8 MeV to 134 MeV, with monochromatic photons obtained by in flight annihilation of monoenergetic positrons. integrated section up tillEγ=140 is (1.59±0.11)σ0, whereσ0 Thomas-Reiche-Kuhn sum-rule. photonuclear absorption evaluated be (1.73±0.15)σ0. behaviour as a function Eγ, 40
