Etymology

From eigen- + volume.

Meanings

1. A volume determined by molecular refraction measurements, based on the assumption that the molecular packing coefficient is constant.
   • Real gas particles have a finite size. When packed as densely as possible they occupy the so-called eigenvolume. The steep rise in pressure shown by the ideal gas equation as V -> 0 must occur in reality when the gas is compressed to its eigenvolume. 2012, Erich W. Schmid, Gerhard Spitz, Wolfgang Lösch, Theoretical Physics on the Personal Computer, →ISBN, page 102:
   • Radiopaque markers implanted in the left ventricle allow one to follow the motion of specific elements of myocardium and compute a measure of relative left ventricular volume, called eigenvolume. 1988, Excerpta medica. Section 14. Radiology - Volume 60, page 81:
   • However, when we apply the eigenvolume corrections with the mass-proportional eigenvolume v#95;i#92;simm#95;i, fixed to the realistic proton hard-core radius r#95;p#92;simeq 0.4-0.5 fm, we observe a second minimum in the temperature dependence of the #92;chi², located at the significantly higher temperatures. 2015, Volodymyr Vovchenko, Horst Stöcker, “Heavy-ion hot hadron matter freezes out at T=170-320 MeV?”, in arXiv:
