Abstract:
In our previous work [1] were evaluated the asymmetry effects in (n,p) reaction on 35Cl and 14N using 2 resonances for 35Cl and 3 resonance for 14N. In the both cases was used the formalism of the mixing states of the compound nucleus with opposites parities. In the first case of 35Cl were evaluated the asymmetry coefficients in the two-level approximation up to 1 keV. These levels are closed and the next resonance is far from these two so we have a quite good agreement between theoretical and experimental data. Will be of interest to obtain the behavior of asymmetry effects higher then 1 keV and with participation of more resonances. In the second case of 14N the resonance are far one from other and our evaluation was realized up to 1 MeV where are present more then 10 resonances. In our last evaluation we used only 3 resonance and the asymmetry effects are results of the interference of two positive resonance with more then 100 keV between them. All these indicate that it is necessary to have an evaluation of the asymmetry effects with participation of all resonance in the neutron energy interval.
