Webb7 dec. 2012 · Abstract. We present neutron scattering measurements of the dynamic structure factor S(Q,ω) of amorphous solid helium confined in 47-Å pore diameter MCM-41 at pressure 48.6 bars. At low temperature T = 0.05 K, we observe S(Q,ω) of the confined quantum amorphous solid plus the bulk polycrystalline solid between the MCM-41 … WebbLiquid and solid helium are prototype simple and solids displaying a wide spectrum of quantum properties. Understanding gained in these simple systems can be readily …
