Noun

eigenvolume (plural eigenvolumes)

1. (physiology) A volume determined by molecular refraction measurements, based on the assumption that the molecular packing coefficient is constant.

     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.

   • 2012, Erich W. Schmid, Gerhard Spitz, Wolfgang Lösch, Theoretical Physics on the Personal Computer, →ISBN, page 102:

     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.

     However, when we apply the eigenvolume corrections with the mass-proportional eigenvolume $v_{i}\sim m_{i}$, fixed to the realistic proton hard-core radius $r_{p}\simeq 0.4-0.5$ fm, we observe a second minimum in the temperature dependence of the $\chi ^{2}$, located at the significantly higher temperatures.
