The material release on the side opposite to the laser drive of a CH shell was probed at conditions relevant to inertial con finement fusion (ICF). The release was discovered to expand further with a longer scale length than that predicted by radiation-hydrodynamic simulations. The simulations reflect that a relaxation of the back side of the shell consistent with measurements explains the experimentally observed reduction in ICF implosion performance|speci cally, reduced areal density at peak compression.
