On psub(1/2) and psub(3/2) components of the neutron strength function

A brief review is presented which demonstrates that it is impossible to observe spin-orbital splitting of 3p-maximum of the neutron strength function without the resonance separation over spins. The sterngth functions for p-resonances with different spins S1(J) are expressed through the strength functions Ssub(1/2)sup(1) and Ssub(3/2)sup(1) for psub(1/2) and psub(3/2) neutrons. The values of Ssub(1/2)sup(1) and Ssub(3/2)sup(1) are obtained from the available experimental data, which are not yet sufficient for a definite conclusion about splitting
