Searching for Neutrinos From Ge-76 to Detect None

There are several projects involving Germanium-76 and monitoring neutrinos from its decay.

Some descriptions include irrelevant references to antimatter.
The goal is essentially the detection of a radioactive decay of two neutrons into 2 protons and 2 electrons with no neutrinos.

Earlier experiments found the electrons did not carry enough energy so a neutrino is proposed to carry that missing energy, and energy is conserved.

'
The GERDA experiment at the Gran Sasso Underground Laboratory is looking for signs of neutrinoless double beta decay. The experiment has the greatest sensitivity worldwide for detecting the decay in question. To further improve the chances of success, a follow-up project, LEGEND, uses an even more refined decay experiment.

While the Standard Model of Particle Physics has remained mostly unchanged since its initial conception, experimental observations for neutrinos have forced the neutrino part of the theory to be reconsidered in its entirety.

Neutrino oscillation was the first observation inconsistent with the predictions and proves that neutrinos have non-zero masses, a property that contradicts the Standard Model. In 2015, this discovery was rewarded with the Nobel Prize.

From another online reference, titled: 'Major steps forward in understanding neutrino properties'
is(some text is in Deutsch):
'
The GERDA experiment is designed to scrutinize the Majorana hypothesis by searching for the neutrinoless double beta decay of the germanium isotope 76-Ge: Two neutrons inside a 76-Ge nucleus simultaneously transform into two protons with the emission of two electrons. This decay is forbidden in the Standard Model because the two antineutrinos – the balancing antimatter – are missing.

The GERDA experiment achieves extreme levels of sensitivity

GERDA is the first experiment to reach exceptionally low levels of background noise and has now surpassed the half-life sensitivity for decay of 10^26 years. In other words: GERDA proves that the process has a half-life of at least 10^26 years, or 10,000,000,000,000,000 times the age of the Universe.

These experiments involve understanding neutrinos in the Standard Model.

I recall Thunderbolts Project is proposing neutrinos for the aether.

Perhaps these experiments will have useful results.
