Fe-55 Beta Decay Acceleration

Posted on January 16, 2021October 20, 2022 by maxfomitchev

55Fe 55Fe is a relatively short-lived isotope that undergoes an inverse beta decays (K-capture) with the half life of 2.737 years. When searching for natural radioactive decay acceleration it is preferable to work with short-lived isotopes like 55Fe because they ... Read More

CapeSym ScintiClear SC-14×25 SiPM Gamma Detector

Posted on November 25, 2020October 20, 2022 by maxfomitchev

As I have stated before, CapeSym SrI2(Eu) scintillation detectors mounted on a silicon photomultiplier (SiPM) are characterized by high resolution and compact form factor. These detectors are easy to work with: they do not require high bias voltage (only 30V for ... Read More

Kromek SPEAR CZT is a compact gamma detector with the useful energy range of 30 keV to about 300 keV, priced just under $2,000 US dollars - Fig. 1. Fig. 1. Kromek SPEAR CZT gamma detector. Although the manufacturer-declared energy ... Read More

The Rich Physics of Cs-137 Gamma Spectrum

Posted on October 24, 2020January 23, 2025 by maxfomitchev

The process of beta decay is an extremely fascinating phenomenon. I cannot think of any other physical process that is so rich in fundamental physics. Please allow me to elaborate. Recommended Tools MCA-PRO (dual-instrument multichannel analyzer, pulse processor, power supply); ... Read More

A Scientist’s Oath

Posted on October 22, 2020October 20, 2022 by maxfomitchev

I have been thinking a lot about stagnation of science and corruption of the academia. I have many colleagues that whisper about rampant toxicity in the academia, ridicule and derision in peer review. How did this happen? Aren't scientists supposed ... Read More

Free Falling Charge Does Not Radiate

Posted on October 21, 2020October 20, 2022 by maxfomitchev

I think I have made an important discovery: a charge free falling in an electrostatic potential does not radiate. The thinking that has lead me to this is profoundly similar to the key principle of General Relativity. By generalizing this ... Read More

The Theory of Universal Aether

Posted on October 1, 2020October 20, 2022 by maxfomitchev

I have been working on this theory for many years, but could not get the vision of the complete theory. Until one day, my lovely wife told me out of the blue "I think you are overlooking an extra dimension". ... Read More

Saint Gobain Enhanced Lanthanum Bromide Detector

Posted on September 13, 2020October 20, 2022 by maxfomitchev

Lanthanum Bromide Advantage Lanthanum bromide scintillators are gaining popularity due to their superior resolution properties. Typical resolution of a LaBr3(Ce) scintillation detector @ 661.7 keV is between 2.5 and 3.5% depending on manufacturer and crystal grade. Thus, LaBr3(Ce) detector resolution ... Read More
