Fission yields in U-235:My data Cs-135: No Depression
My hypothesis:
50132Sn82 – Double-magic!
Sn-132 ought to be specially favoured
Leading to a “mirror peak” at about 101, 102

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.
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!
