[Part I by the authors and \textit{P. M. Soardi} in Trans. Am. Math. Soc. 353, No. 1, 349-364 (2000; Zbl 0959.22005)]. Let \(\pi\) be the tensor product of two spherical irreducible unitary representations of the automorphism group \(G\) of a homogeneous tree. The authors describe the discrete series representations of \(G\) which appear as sub-representations of \(\pi\).
