And very not mine - sorry.
> database of nuclear isomer energy levels [-> identify element(s) -> improve search odds]
A good idea. My extremely fuzzy recollection is the two-ish were stable-ish mid-weight elements. But it's been a long time.
Thank you for the suggestion. If I go down this path again (for a WebVR page to teach size/scale?), I may try that. Another possibility is to find and ask more people with a related research focus. I'd just hoped that with a relevant HN thread, someone might reply "oh, sure, that's on my shelf; let's see, it's ...". :)
