ResumoThe role of the annealing atmosphere on the electrical resistivity minimum of copper was studied. The experimental techniques for these measurements are briefly described. The samples consisted of 0.05-cm diameter copper wire of 25-cm length wound around a quartz tube. The specimens were annealed in an evacuated mullite tube which allowed for annealing in desired atmospheres by means of a controlled leak. A temperature range from 1.7 to 25.0 deg K was covered.
