Description
The production of the light p-nuclei 113In and 115Sn has been a long-standing problem for $\gamma$-process nucleosynthesis [1,2]. The reaction flow in the Cd-In-Sn region is rather complicated due to the existance of several long-lived $\beta$-decaying isomers, which leads to a general underproduction of these isotopes compared to the other p-nuclei. In this talk, I will discuss the current status of the origin of 113In and 115Sn along with their different production mechanisms and a recent experimental measurement regarding the production of 113In [3].
