## Efimov Factor

**efimovFactor** is the universal scaling factor associated with Efimov states in three-body quantum systems.

## Specialized physics

It is dimensionless and applies only under specific few-body conditions. Use [pow()](https://calcul.io/function/pow/index.md) for repeated scaling and keep it distinct from ordinary molecular constants such as [boltzmann](https://calcul.io/constants/boltzmann/index.md).
