Summary

The measurements were performed on samples prepared in the way which, in the authors' opinion, diminishes non-reproducibility of the transition temperature; by encapsulation of indium samples into glass cells a critical temperature reproducibility better than more or less 0.1 milliK is obtained. These results led the authors to propose the use of the superconducting transition of indium for calibration of an interpolating gas thermometer, realizing the International Temperature Scale 1990 in the temperature range 3-25 K.
