    "abstract": "This paper is devoted to the study of quantum dissipation in cluster decay\nphenomena in the frame of the Lindblad approach to quantum open systems. The\ntunneling of a metastable state across a piecewise quadratic potential is\nenvisaged for two cases : one and two harmonic wells smoothly joined to an\ninverted parabola which simulates the barrier. The width and depth of the\nsecond harmonic oscillator well was varied over a wide range of values in order\nto encompass particular cases of tunneling such as the double well potential\nand the cluster decay. The evolution of the averages and covariances of the\nquantum sub-system is studied in both under- and overdamped regimes. For a\ngaussian intial wave-packet we compute the tunneling probability for different\nvalues of the friction coefficient and fixed values of the diffusion\ncoefficients.",
