Abstract：
The theoricians¹⁾ have found that the virtual excitation of GR plays an important role in ⁸⁷Sr(n, n')^87mSr inelastic scattering, the target with a hole in a neutron close shell, even when the incident neutron energy is around 3 MeV. The cross section of ⁸⁷Sr(n, n')^87mSr (9⁺/2 1^－/2) is calculated, for compound nucleus' with H-F formula, for GR'S with phenomenological as well as microscopical method, but there are no experimental data could compare with them directly yet.
We measure the total inelastic cross section with activation method for En<2 MeV, which lead to those levels that decay through the first exdited state (1/2^－), i.e. the metastable state with a half live of 2.83 hours. Together with the data given by J. K. Temperley et al ⁵⁾, we present the total eycitation curve.
