Abstract:
The $$\gamma $$ γ -ray strength function ( $$\gamma $$ 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– $$\gamma $$ γ coincidence events from the $$\mathrm {d}(^{86}\mathrm {Kr}, \mathrm {p}\gamma )^{87}\mathrm {Kr}$$ d ( 86 Kr , p γ ) 87 Kr reaction were measured at iThemba LABS and the $$\gamma $$ γ SF and NLD in $$^{87}\mathrm {Kr}$$ 87 Kr was obtained. The low-energy region of the $$\gamma $$ γ SF is compared to shell-model calculations, which suggest this region to be dominated by M1 strength. The $$\gamma $$ γ SF and NLD are used as input parameters to Hauser–Feshbach calculations to constrain $$(\mathrm {n},\gamma )$$ ( n , γ ) cross sections of nuclei using the TALYS reaction code. These results are compared to $$^{86}\mathrm {Kr}(n,\gamma )$$ 86 Kr ( n , γ ) data from direct measurements.
