Helium-3 and the Liquid Helium Problem

Abstract

Helium-3 and the Liquid Helium Problem Is a break-through into the liquid helium problem imminent?In 1908 when Kamerlingh Onnes first liquefied helium (70), the Leyden workers must have been exhilarated also by the achievement of having at last produced what was expected to be the simplest liquid imaginable-one in which the molecules were spherically symmetric, chemically unreactive, and bound together by forces an order of magnitude smaller than in any other known liquid.
