Abstract	A classical, phenomenological description of a short-range radial force associated with an isolated neutron is presented. The force is defined exclusively in the region external to the neutron core surface radius and is treated as a function of radial distance within the diffuse outer region. Empirically observed features—negligible force beyond a finite range, rapid variation over a narrow radial interval, and absence of long-range behavior—are captured using an exponential radial force profile. The characteristic transition length is motivated by known structural length scales of the neutron’s outer region and is not introduced as a fitting parameter. Although the mathematical form is Yukawa-like, the present formulation does not invoke mediator exchange, and is intended solely as a minimal, force-based classical representation of short-range behavior.
Keywords	Short-range force; neutron radial force; exponential force profile; phenomenological model; nuclear length scale; Yukawa-like behavior.
