My hypothesis:
50132Sn82 – Double-magic!
Sn-132 ought to be specially favoured
Leading to a “mirror peak” at about 101, 102

So I learned that I had been right
-- or perhaps not.

Tin Isotopes
Identified Tin -132, 133, 134
In Norway
But the fission yields not determined

By Charles’ example:
I learned
Things that cannot be taught.
![Page 23: So I learned that I had been right -- or perhaps not](https://reader036.vdocuments.us/reader036/viewer/2022081515/56816153550346895dd0db3b/html5/thumbnails/23.jpg)
What did I learn under Charles’ care?
Be imaginativeFollow my own intuitionThink and write clearly
Question established ideasNo one tells me how to think
People are interesting
and more

Thank you Charles!
