Liquid hydrogen isotopes layer profile inside a cryogenic inertia confinement fusion capsule for an isothermal environment

It has been shown that the Young-Laplace equation based on the balance of t he gravitational force and interfacial tension alone cannot produce a valid solution for the profile of a continuous liquid hydrogen layer inside an i nertia confinement fusion capsule shell. In the calculated results, the Lon don-van der Waals forces between the liquid and solid (shell) molecules mus t 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 isot opes layers. It has been also shown that, in an isothermal environment, a c ontinuous 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 molecul es is infinity.
