A comparison of different parametrized pocket formulae to calculate fusion barriers

Using twelve different parametrized pocket formulae fusion barrier heights and positions are calculated and confronted with available experimental data. All different parametrized pocket formulae are able to reproduce fusion barrier heights and positions within ±10% and ±20%, respectively. Our detailed study investigate that the parametrized pocket formulae based on models such as Bass 1980, Winther 1995, Prox 1988, and Royer 2001 reproduce the barrier heights nicely as compared to other formulae available in the literature.
