Experimental indication of anomalous sensitivity in many-body systems: Deterministic randomness in complex quantum collisions?

TL;DR

This study experimentally investigates potential anomalous sensitivity in heavy ion collision cross sections, revealing significant variability across different beam spots, which may suggest deterministic randomness in complex quantum interactions.

Contribution

It provides experimental evidence for anomalous sensitivity in dissipative heavy ion collisions, a phenomenon not previously confirmed.

Findings

Significant differences in cross sections across beam spots

Evidence suggesting deterministic randomness in quantum collisions

Highlights need for further experimental investigation

Abstract

We have experimentally tested a recently suggested possibility for anomalous sensitivity of the cross sections of dissipative heavy ion collisions. Cross sections for the $^{19}$F+$^{27}$Al dissipative collisions were measured at the fixed energy 118.75 MeV of the $^{19}$F for the 12 different beam spots on the same target foil. The data demonstrate dramatic differences between the cross sections for the different beam spots. The effect may indicate deterministic randomness in complex quantum collisions. New experiments are highly desirable in a view of the fundamental importance of the problem.
