Measurement of the Boltzmann Constant in a Quasispherical Acoustic Resonator

Frequencies of acoustic and electromagnetic resonances were measured in a quasispherical acoustic resonator at the temperature of the triple point of water. The resonator was filled with helium 4 He. Based on the analysis of experimental data, a value for the Boltzmann constant of k B = 1.380651·10...

More Information
Summary:Frequencies of acoustic and electromagnetic resonances were measured in a quasispherical acoustic resonator at the temperature of the triple point of water. The resonator was filled with helium 4 He. Based on the analysis of experimental data, a value for the Boltzmann constant of k B = 1.380651·10 –23 J·K –1 with uncertainty of 2.4 ppm was obtained.
