  We prove that basket links, whose symmetrized Seifert form is congruent to
the Cartan matrix of the simply laced Dynkin diagram $A_{n}$, are isotopic to
the torus link $T(2,n+1)$. In addition, we provide examples of links,
constructed by plumbing $n$ positive Hopf bands the core curves of which
intersect at most once, with symmetrized Seifert form congruent to the Cartan
matrix $A_{n}$, that are not isotopic to $T(2,n+1)$.
