Abstract
A rigorous proof is presented which shows that the classical Young–Laplace equation cannot predict a continuous liquid layer inside a spherical‐shell container. An augmented Young–Laplace equation is in turn derived to describe the equilibrium profiles of a continuous liquid hydrogen layer inside a spherical‐shell inertial fusion target. The augmentation is achieved by adding to the total free energy a term originating from the attractive intermolecular forces of the van der Waals type.Keywords
