    "abstract": "Following the Caldeira-Leggett approach to describe dissipative quantum\nsystems the structure function for a harmonic oscillator with Ohmic dissipation\nis evaluated by an analytic continuation from euclidean to real time. The\nanalytic properties of the Fourier transform of the structure function with\nrespect to the energy transfer (the ``characteristic function\u0027\u0027) are studied\nand utilized. In the one-parameter model of Ohmic dissipation we show\nexplicitly that the broadening of excited states increases with the state\nnumber without violating sum rules. Analytic and numerical results suggest that\nthis is a phenomenologically relevant, consistent model to include the coupling\nof a single (sub-)nuclear particle to unobserved and complex degrees of\nfreedom.",
