Location of He Atoms in a Metal Vacancy
Recent lattice location experiments of 3He in tungsten1 show that the equilibrium position of the implanted He atom is neither substitutional nor simple interstitial. We have previously reported binding energies for up to four He atoms in a vacancy.2 Here we discuss the minimum energy configurations resulting from irrultiple-He-atoms clustering in the hope of aiding in the interpretation of these experimental results.
