, , , , , , and . Though and are also potential isotopes to be observed, their production in supernova explosions has already been extensively studied [@Magkotsios_2010; @2006ApJ...640..891Y]. The decay properties of these isotopes used in this study are given in Table \[tab:decay\], where the decay energies and branching ratios come from the National Nuclear Data Center at Brookhaven National Laboratory (ENSDF evaluated properties).
