First application of the Oslo method in inverse kinematics

The γ-ray strength function (γ SF) and nuclear level density (NLD) have been extracted for the first time from inverse kinematic reactions with the Oslo method. This novel technique allows measurements of these properties across a wide range of previously inaccessible nuclei. Proton-γ coincidence events from the d(86 Kr, pγ) 87 Kr reaction were measured at iThemba LABS and the γ SF and NLD in 87 Kr was obtained. The low-energy region of the γ SF is compared to shell-model calculations, which suggest this region to be dominated by M1 strength. The γ SF and NLD are used as input parameters to Hauser-Feshbach calculations to constrain (n, γ) cross sections of nuclei using the TALYS reaction code. These results are compared to 86 Kr(n, γ) data from direct measurements.

The γ-ray strength function (γSF) and nuclear level density (NLD) have been extracted for the first time from inverse kinematic reactions with the Oslo Method. This novel technique allows measurements of these properties across a wide range of previously inaccessible nuclei. Protonγ coincidence events from the d( 86 Kr, pγ) 87 Kr reaction were measured at iThemba LABS and the γSF and NLD in 87 Kr obtained. The nature of the low-energy region of the γSF is explored through comparison to Shell Model calculations and is found to be dominated by M1 strength. The γSF and NLD are used as input parameters to Hauser-Feshbach calculations to constrain (n, γ) cross sections of nuclei using the TALYS reaction code. These results are compared to 86 Kr(n,γ) data from direct measurements.
