The ionisation of helium by neutral helium atoms
1944A method is described for investigating the ionisation produced in helium by collisions between quasi-stationary atoms of helium - that is, atoms possessing only thermal velocities - and a beam of neutral helium atoms with kinetic energy less than one hundred electron volts. Ionisation is shown to begin when the kinetic energy of the impinging particle

Helium-3 in Superfluid Helium-4
1974This paper is not intended to be a review nor is there sufficient time or space to give an adequate introduction to the work which will be described in the many contributed papers at the conference, so I will confine myself to some topics that have interested our group at Ohio State.
