It is shown that the difference between the experimental capture cross section and the impulse approximation strongly depends on the hard core of the NN interaction. Use of hard core wave functions is not sufficient to explain quantitatively the experimental result. The exchange potential itself has to be modified for small nucleon distances. 相似文献

A formula for the calculation of the cross sections,of nuclear transition to continuum states induced by direct radiative capture of intermediate-energy proton is deduced.The transition amplitude includes two terms corresponding to potential-scattering to potential-scattering transitions and potential-scattering to resonance-scatting transitions,respectively.The model is compard with available experimental data of the 11B(p,γ19)12C reaction,and the results show that the direct capture mechanism is capable to account for the main features of the measured data within the reasonable parameter scope,and,in the present case,the contributions from two terms are of the same order of magnitude.The physical significance of the results is also discussed. 相似文献

The transition operator for the radiative capture of mesons by protons is constructed starting from a chiral Lagrangian of the system obtained within the approach of hidden local symmetries. The transition operator is gauge invariant and its hadron
radiative part satisfies exactly two relevant continuity equations.
