INTRODUCTION
============

Although fission barrier heights $B_{f}$ are not directly measurable quantities, i.e. are not quantum observables, they are very useful in estimating nuclear fission rates. As the activation energy $E_a$ (per mole) in chemistry gives a rate $k$ of a chemical reaction at temperature $T$ via the Arrhenius law: $k=Ae^{-E_a/RT}$ ($R$ - the gas constant; $A$ - the frequency factor) [@tHoff; @Arrhe], the fission barrier gives the fission rate $\Gamma_f$ of an excited (as they usually are in nuclear reactions) nucleus via: $\Gamma_f\sim e^{-B_f/kT_{eff}}$, where $T_{eff}$ is an effective temperature derived from the excitation energy, and $k$ - the Boltzman constant. For example, knowing fission barriers of possible fusion products helps predicting a
