Comment on an Effect Proposed by A.G. Lebed in Semiclassical Gravity

TL;DR

This paper critically examines A.G. Lebed's proposed gravitational effect on hydrogen atoms, revealing inconsistencies with existing experimental and astronomical data, and discusses implications for nuclear excitations and Earth's motion effects.

Contribution

It provides a critical analysis of Lebed's effect, highlighting contradictions with prior experimental results and astronomical observations.

Findings

Lebed's effect implies nuclear excitations not supported by experiments.

Predicted effects conflict with underground radiation detector data.

Astronomical observations do not support the proposed effect.

Abstract

A.G. Lebed has given an argument that when a hydrogen atom is transported slowly to a different gravitational potential, it has a certain probability of emitting a photon. He proposes a space-based experiment to detect this effect. I show here that his arguments also imply the existence of nuclear excitations, as well as an effect due to the earth's motion in the sun's potential. This is not consistent with previous results from underground radiation detectors. It is also in conflict with astronomical observations.
