I would like to ask on the recent discoveries of Bose-Einstein Condensates : It is reported that Rb-85, Rb-87, NA-23, Li-7, are bosons, while to my understanding they contain odd numbers of protons and/or neutrons, which should cause them to be fermions instead.
Don't forget to count the electrons.
The criterion is an even number of fermions (not just an even
number of protons and/or neutrons).
Feynman volume III chapter 4.
