Description of high-lying one-hole states in 1p-shell nuclei

Interaction with 1s shell by means of (p, 2p) reaction at middle energies is studied. Data from (p, 2p) reaction on 7Li, 9Be, 12C, 14N, 16O target-nuclei within the framework of plane-wave approximation are analyzed using spectroscopic factors to knock out a nucleon from 1s shell. Two sets of wave functions of states of anomalous parity in the nuclei of 1p shell calculated in configuration space of all the physical 1 hw excitations by means of two considerably differing hole-particle interactions, non-central and pure central are used for studying the shape of differential cross section curve of the (p, 2p) reaction in the region of proton knocking out from the strong-connected 1s shell. It is shown, that non-central interaction only can give the unitary description of experimental data available
