    We can deduce that there is magnetic hyperfine inteaction. I and J couple to form F. since the levels splits up in 3 pieces, we conclude that I en J both are 1 in order to form F=0, 1, 2.

    At low enough temperature thermal energy will no be sufficient to overrule the small energy splitting. Nuclei wil now be able to go to their lowest energy state. So we will get an anisotropic population of the nuclear orientation. There will be more nclei with spin projection +1 than with spin projection -1.
