Abstract
The first experimental and theoretical investigation of the difference in t he temperature behavior of the linear expansion coefficients of single crys tals grown from isotopically highly enriched and natural germanium is repor ted. A comparison of the data for Ge-70 and Ge-nat crystals reveals the sig nificant influence of isotopic composition over a wide range of temperature s 30-230 K. (C) 1999 American Institute of Physics.
