text: Yo, check it out, I got some knowledge to share,
  'Bout solutions to the radiation diffusion equation, I swear.
  We talkin' 'bout the absorbed energy, they call it "wall loss,"
  In an inertial confinement fusion, no matter the cost.
  
  Supersonic or subsonic, which one's the way to go?
  Well, listen up, 'cause I got the info you need to know.
  A high metallic foam as the hohlraum wall material,
  It'll reduce hydrodynamic losses, that's the real deal.
  
  Net absorbed energy, we gotta make it higher,
  So we derive an analytic expression, set it on fire.
  Optimal density, that's the key to our success,
  For any drive temperature and pulse-length, nothin' less.
  
  Numerical simulations, they back up what we say,
  This reduction factor brings us closer every day.
  We're talkin' 'bout increasin' the coupling efficiency,
  Of indirectly driven ICF capsules, that's the efficiency.
  
  So remember these words, let 'em sink in deep,
  Solutions to the radiation diffusion equation, they'll keep.
  With a high metallic foam and optimal density in sight,
  We're pushin' the boundaries, takin' fusion to new heights.
