Isomer energy level(continue)

[hanhechong (鹤冲 韩)]

Dear professors,
Continue the discussions in this post Isomer energy level, I want to raise two issues concerning the isomer of Sb120 and Sb118 respectively.

1. For Sb120
   

   
   
   
   
   
   I encountered this two lines in usrrnc.f. I want to confirm if it is Sb120[0+X] according to G4 database as it not only is the lowest isomer level, but also is able to decay to Sn120 as the next line.

2. For Sb118
   

   
   
   
   
   
   I also have these two similar lines. This time, however, Sb118[250] is not the lowest level. But on the other hand, it’s the only one which can decay to Sn118 as the next line. So what exactly is this 51,118,1?

Thank you for your help!
Best regards,
Hechong Han
