Thermal expansion of solid solutions of nitrogen in argon (0.51; 2.24; 4.89% ¹⁴N₂) has been investigated in the temperature range 1-16 K. An impurity contribution Да to a linear expansion coefficient has been separated. Negative values of Δα at T < 4.3 К for the solution with the nitrogen concent...
