Searching for ($\gamma$,$\alpha$)/($\gamma$,n) branching points in the $\gamma$-process path around A=100

In order to model the $\gamma$-process it is important to determine the branching points along isotopic chains. The $^{90}$Zr($\alpha$,$\gamma$)$^{94}$Mo, $^{102}$Pd($\alpha$,$\gamma$)$^{106}$Cd, and $^{108,110}$Cd($\alpha$,$\gamma$)$^{112,114}$Sn cross sections were measured to determine if $^{94}$Mo, $^{106}$Cd, and $^{112,114}$Sn were branching points in the $\gamma$-process reaction flow. The reactions were measured at the University of Notre Dame using the High EfficienCy TOtal absorption spectrometeR (HECTOR). The $^{90}$Zr($\alpha$,$\gamma$)$^{94}$Mo and $^{108}$Cd($\alpha$,$\gamma$)$^{112}$Sn measurements extended the range of previously measured cross sections down to lower energies and the $^{102}$Pd($\alpha$,$\gamma$)$^{106}$Cd and $^{110}$Cd($\alpha$,$\gamma$)$^{114}$Sn reactions were measured for the first time. The measurements were compared to theoretical models from Talys 1.9. The ($\gamma$,$\alpha$) and ($\gamma$,n) rates were then calculated using the best fit model and compared in order to investigate the relative intensity between the reaction pathways. It was found that in all cases the ($\gamma$,$\alpha$) reaction pathway begins to dominate within the temperature range of 1.5-3.5 GK.
