Abstract

We study the transparency $T$ of nuclei for nucleons knocked-out in high-energy semi-inclusive $(e, e^{'} p)$ reactions, using an improved theoretical input, discussed by Nikolaev et al. We establish that neglect of $N N$ -correlations between the knocked-out and core nucleons reduces nuclear transparencies by $\approx 15%$ for light, to $\approx 10%$ for heavy nuclei. About the same is predicted for transparencies, integrated over the transverse or longitudinal momentum of the outgoing proton. Hadron dynamics predicts a roughly constant $T$ beyond $Q^{2} \approx$ 2 GeV $^{2}$ , whereas for all targets the largest measured data point $Q^{2}$ =6.7 GeV $^{2}$ appears to lie above that plateau. Large error bars on those data-points preclude a conclusion regarding the onset of colour transparency.
