For calculating (p,nx) and (n,px) reactions into Intranuclear cascade model, I investigated the isovector giant resonance, which was considered the case of underestimation forward angle the less than 30 degrees.

The purpose of this study is to improve the reproducibility of double differential cross sections by introducing isovector giant resonance.

The method of calculation, three kinds of isovector giant resonances with L=0, 1, 2 were introduced into the INC model.

Three giant resonances were generalized by using these relationships because it was found that the probability of occurrence and each excitation energy were related to the incident energy and the neutron surplus number in the nucleus.

As a result, the reproducibility of the experimental values for27Al,90Zr,208Pb target nuclei for the (p,nx) reaction was improved and the (n, px) reactions can be reproduced in a wide range of target nuclei from 12C to 181Ta under tens to hundreds of MeV injection.
