Description

Gamma strength function is the important input parameter to determine the photodisintegration rate and neutron capture rate for astrophysics and nuclear technologies. To test the model calculation, photon-scattering cross sections were measured for 139La up to the neutron separation energy with bremsstrahlung at an electron kinetic energy of 11.5 MeV. Scattered photons were measured with four 100% HPGe detectors, and 11B is used to determine the γ flux. The experimental data was analyzed with statistical methods to obtain the intensities of the ground-state transitions and their branching ratios. The present 139La photon scattering cross sections are combined with 139La photoneutron cross sections.
