Possible Measurement of the Probability of P-States in the Ground State of 4He Nucleus
Using the experimental data on the total cross-sections of 4He(y, p)3H and 4He(y, n)3He reactions with S = 1 transitions as the base, we discuss the possibility of measuring the probability of 3P0-states in the ground state of 4He nucleus. The analysis of the experimental data has suggested the conclusion that, within the statistical error, the ratio of the cross section of the reaction in the collinear geometry to the cross section of the electrical dipole transition with the spin S = 0 at the angle of the emission of nucleons 0N = 90∘vp and vn in the range of photon energies 22 ≤ Ey ≤ 100 MeV does not depend from the photon energy. This is in agreement with the assumption that the S = 1 transitions can originate from 3P0 states of 4He nucleus. The average values of vp and vn in the mentioned photon energy range are calculated as vp = 0 .01 ± 0 .002 and vn = 0 .015 ± 0 .003 (the errors are statistical only).
