Based on the construction of infinite dimensional balanced realizations an alternative solution to the following inverse spectral problem is presented: Given a monotonically decreasing sequence of positive numbers (σn)n ≥ 1, does there exist a Hankel operator whose sequence of singular values is (σn)n ≥ 1?</p
