> After looking through >800 shots from Jul 2nd 21h to Jul 3rd 05h, we couldn't find a single example of a "smoking gun" isomer decay. I.e. I'm talking about the examples Liliana posted earlier. We did find many examples (roughly 10%) where the ion track spontaneously 
> disappeared, but this shouldn't be the isomer as there was no frequency shift.
> 
> We did, as Iris mentioned, observe some line "in-between" the broad peak unique to the 410MHz, and listed them here (https://triumfoffice365-my.sharepoint.com/:x:/g/personal/dillmann_triumf_ca/EdKsMfSC3AlHopA36PdLBlsBE2MCSY0hh5qIsuau5HFBmg?rtime=Z2os4J492Ug).
> I then proceeded to sum these files to see if they lined up. The result it attached, with the previous total sum from 21-00h Jul 2nd at the bottom for comparison. It seems the 70Se line has shifted, this is observed in the other shots too. However, despite the low 
> statistics, these other shots don't line up with the broad peak identified before, although they don't line up well with each other individually either.
> In either case, we think these files might be worth offline analysis as they're the only possible hint of the 70Se isomer so far.
