Abstract
The cross section for the excitation of the 0.8-sec metastable state of by inelastic neutron scattering has been measured for neutron energies up to 3.1 Mev. Neutrons were produced by the reaction. The lowest neutron energy for which excitation is observed is 1.6 Mev. This is in agreement with the level scheme for based on other information. For the first 800 kev above threshold, the cross section rises approximately linearly, attaining a value of 75 millibarns at 2.4 Mev. After leveling off, it abruptly increases at 2.75 Mev and has a value of 190 millibarns at 3.1 Mev. It is judged that the absolute values of the cross section are accurate to ±40 percent. The absolute cross section for excitation of the metastable state as a function of neutron energy is calculated by the use of the strong interaction theory of nuclear reactions. The theoretical predictions agree well with the measured curve.
