    "abstract": "We address the problem of collective motion across a barrier like encountered\nin fission. A formula for the quantal decay rate is derived which bases on a\nrecently developed variational approach for functional integrals. This formula\ncan be applied to low temperatures that have not been accessible within the\nformer PSPA type approach. To account for damping of collective motion one\nparticle Green functions are dressed with appropriate self-energies.",
