It has been shown that the Young-Laplace equation based on the balance of the gravitational force and interfacial tension alone cannot produce a valid solution for the profile of a continuous liquid hydrogen layer inside an inertia confinement fusion capsule shell. In the calculated results, the London-van der Waals forces between the liquid and solid (shell) molecules must be included in the equation. The retardation effect of the London-van der Waals forces needs to be taken into account for thick liquid hydrogen isotopes layers. It has been also shown that, in an isothermal environment, a continuous liquid hydrogen isotopes layer with a uniform thickness can only be achieved inside the capsule shell, such as the spherical glass when the gravity is zero or the London constant between the solid and liquid molecules is infinity.
