Abstract
Lattice parameters, thermal expansion coefficients, and Grüneisen parameters of tungsten are determined by an x‐ray method in the temperature range of 180–40 K without the use of liquid gases. Lattice parameters are expressed as a function of temperature. Thermal‐expansion coefficients decrease with temperature and show no anomaly in contrast to a hypothesis proposed by Featherston and Neighbours. Grüneisen parameters γ are decreasing with temperature in accordance with the theoretical predictions.This publication has 8 references indexed in Scilit:
