Autoionization of He and Autodetachment of He- following Bombardment by H+, H2+, He+, and He Atoms

Heat Flow in a He Ii Filled Fin*

The excellent heat removal capability of pressurized superfluid helium, HeIIplVg, has led in recent years to its use as a coolant in fusionlo and acceleratorll magnets where the operating temperature is typically in the range of 1.8 to 2. K. More recently, He-IIp has been proposed as the coolant for a polarized proton target at temperatures as low as 0.5K12. In all cases the HeIIp acts as an ai...

Calculations of the binding energies of weakly bound He–He–H, He–He–H− and He–H–H molecules

We searched for the existence of weakly bound He–He–H, He–He–H− and He–H– H molecules where the binding energies are expected to be of the order of degrees Kelvin. By employing the best empirical interaction between each pair of particles, we solved the Schrödinger equation for the triatomic systems using hyperspherical coordinates in the adiabatic approximation. We found no bound states for 4H...

He/he Production Ratios by Tetrahedral Symmetric Condensation

The present paper treats application of the EQPET (Electronic Quasi-Particle Expansion Theory) model for TSC (Tetrahedral Symmetric Condensate) of H/D mixed systems for Pd host metal. Production ratios of He/He for multi-body fusion reactions in H/D mixed TSC systems are calculated as a function of H/D mixing rate. The model is further extended to treat direct nuclear interactions between host-...

Thermodynamics of Liquid 'he- " He Mixtures

The osmotic pressure of 3He-4He solutions is shown to follow in a natural way from the separation of the specific heat in a quasiparticle contribution and a 4He-contribution. Expressions for important thermodynamic properties such as the chemical potentials, the internal energy, the entropy, specific heat, osmotic pressure, etc. are given for the case the quasiparticle gas can be treated as a n...
