Theoretical and Experimental Studies of Stabilized Metastable Helium.
Abstract
Numerical calculations have shown that the atomic phase of He IV (bulk spin-polarized triplet helium) should have a face-centered cubic crystals structure. A new, metallic phase of He IV has been discovered and shown to have lower energy than the atomic phase. A fundamental model of metallic He IV has been formulated which includes electron spin-spin and spin-orbit interactions as well as the coupling to the radiation field. The problem of metastability of metallic He IV has been formulated mathematically and will be used for future numerical calculations. A physical mechanism has been identified which might be instrumental in stabilizing metallic He IV. Originator supplied keywords include: Metastable helium; Energy storage; Spin polarization; Metastability; Collective effects.
