Quasiparticle Interactions in Two - Dimensional 3 He on 4 He Films
M. Dann, J. Nyéki,* B. P. Cowan, and J. Saunders Millikelvin Laboratory, Department of Physics, Royal Holloway University of London, Egham, Surrey, TW20 0EX, United Kingdom (Received 28 January 1999) Measurements are reported of the heat capacity of 3He bound to an atomically layered 4He film on the surface of graphite. At 3He coverages n3 , 4 nm22, the 3He forms a uniform 2D Fermi system. Ther...
متن کاملStability of (3)He(2)(4)He(n) and (3)He(3)(4)He(n) L=0 clusters.
We have studied the stability of mixed (3)He/(4)He clusters in L=0 states by the diffusion Monte Carlo method, employing the Tang-Toennies-Yiu He-He potential. The clusters (3)He(4)He(N) and (3)He(2)(4)He(N) are stable for N>1. The lighter atoms tend to move to the surface of the cluster. The minimum number of 4He atoms able to bind three 3He atoms in a L=0 state is nine. Two of three fermionic...
متن کاملComment on “Apatite He/He and (U-Th)/He Evidence for an Ancient Grand Canyon”
Flowers and Farley (Reports, 21 December 2012, p. 1616; published online 29 November 2012) use thermochronometry to propose that the western paleo–Grand Canyon was nearly as deep 70 million years ago (Ma) as today. However, lithologies, facies relations, geomorphology, and paleotopography of Miocene interior-basin deposits near the mouth of the Grand Canyon show that no paleocanyon existed in t...
متن کاملThe Evolution of 3 He , 4 He and D in
In this work we present the predictions of a modified version of the “two-infall model” (Chiappini et al. 1997) for the evolution of He, He and D in the Galaxy, as well as their distributions along the Galactic disk. In particular, we show that when allowing for extra-mixing process in low mass stars (M< 2.5 M⊙), as predicted by Charbonnel and do Nascimento (1998), a long standing problem in ch...
متن کاملStructure and energetics of mixed 4 He - 3 He drops
Using a finite-range density functional, we have investigated the energetics and structural features of mixed helium clusters. The possibility of doping the cluster with a molecule of sulfur hexafluoride is also considered. It is seen that the repulsion introduced by the impurity strongly modifies the properties of the smallest drops. Although only a qualitative comparison is possible, the gros...
