Do thermal fluctuations destroy the concept of a critical angular momentum?

We estimate the influence of thermal fluctuations in heavy-ion induced deep inelastic and fusion reactions by means of a one-dimensional Fokker-Planck equation. Approximating the fusion barrier by an inverted harmonic oscillator, we find an expression for the range of angular momenta ΔJ over which t...

Description
Summary:We estimate the influence of thermal fluctuations in heavy-ion induced deep inelastic and fusion reactions by means of a one-dimensional Fokker-Planck equation. Approximating the fusion barrier by an inverted harmonic oscillator, we find an expression for the range of angular momenta ΔJ over which the transmission coefficient falls from 1 to 0. Numerically, ΔJ is fairly but not insignificant, and becomes larger for incident energies near the barrier.
