Abstract：
A computer code OMHFISO, based on optical model and Hauser-Feshbach theory with width fluctuation correction (WHF), is made for calculating neutron reactions of isomer target below 5MeV, in which both the incoming and outgoing particles can be n, p, d, t, ³He and ⁴He. Up to now, there are only few people to calculate the complete set of neutron nuclear data of isomer target. In this work, neutron nuclear data of six isomer targets of unstable isotopes ⁹⁰Rb and ^{91,93,96,97,98}Y are calculated, and reasonable results in physics are obtained.
