In this work, it is pointed out that the ground state of $$n$$ neutrons and n protons in a single-$$j$$ shell, interacting through an isoscalar ($T=0$) pairing force, is not paired, $J=0$, but rather spin aligned, $J=n$. This observation is explained in the context of a model of isoscalar $P(J=1)$ pairs, which is mapped onto a system of $$p$$ bosons, leading to an approximate analytic solution of the isoscalar-pairing limit in $jj$ coupling.
