Neutrons from Piezonuclear Reactions

TL;DR

This study demonstrates neutron emission from cavitating water solutions of iron salts, supporting the existence of piezonuclear reactions induced by pressure and shock waves, with reproducible results and specific threshold behaviors.

Contribution

First experimental evidence of neutron emission from cavitation in iron salt solutions, highlighting features of piezonuclear reactions such as threshold behavior and absence of gamma radiation.

Findings

Neutron emission exceeds background levels during cavitation.

Neutron production shows threshold behavior in power, energy, and time.

Neutron emission occurs without gamma radiation.

Abstract

We report the results obtained by cavitating water solutions of iron salts (iron chloride and iron nitrate) with different concentrations at different ultrasound powers. In all cases we detected a neutron radiation well higher than the background level. The neutron production is perfectly reproducible and can at some extent be controlled. These evidences for neutron emission generated by cavitation support some preliminary clues for the possibility of piezonuclear reactions (namely nuclear reactions induced by pressure and shock waves) obtained in the last ten years. We have been able for the first time to state some basic features of such a neutron emission induced by cavitation, namely: 1) a marked threshold behavior in power, energy and time; 2) its occurring without a concomitant production of gamma radiation.
