Cluster knockout nuclear reactions and momentum distribution of clusters in atomic nuclei

The momentum distribution of deuteron- and α-clusters obtained in theoretical correlation methods are fitted in calculations of the cross sections of deuteron- and α-knockout reactions with electrons. It is shown that the predictions for the momentum distributions at low momenta (0 ≤ k ≤ 0.3 fm-1) are in a qualitative agreement with the cluster momentum distribution found to give the best fit of the experimental data for the cross sections of the Li(e,e'd) and Li(e,e'α) reactions and with other calculations. 5 figs., 29 refs
