Transmission of gamma-quanta through vibrating target

Abstract

The transmission of the Mössbauer γ-quanta through a vibrating absorber is analyzed in the framework of the quantum theory. For this aim the photons are described by the Bialynicki-Birula's wave function. We calculated time dependence of the wave packets, which describe the transmitted γ-photons. It is shown that the squared modulus of their wave function determines the detection rate of γ-photons in full analogy with particles having a mass. The effect of anomalous transmission of Mössbauer radiation, caused by high-frequency periodic swings of the absorber, and the corresponding suppression of reactions is studied.

Transformation of Mössbauer γ-ray photon waveform into short pulses in dual-tone vibrating resonant absorber

“…In accordance with the discussed technique, we describe the electric field of γ-ray photon as a single-photon wave packet within the classical plane wave approximation [2,5,[24][25][26]29], which is equivalent to the complete quantummechanical approach for the problem under consideration [30,31]. Then, in front of the absorber the electric field of the 14.4-keV photon spontaneously emitted without recoil by the radioactive nucleus can be presented in the form [5,24,25]:…”

Production of the178m2Hf isomer using a 1.2 GeV electron accelerator

“…As for the theoretical papers [10 and references therein], they mainly reject the possibility of 178m2 Hf isomer depletion by x-rays. Note, however, that [11] and the recent article [12] show the reality of such a triggering.…”

Observation of enhanced activity of the 178m2Hf isomeric target after its irradiation by bremsstrahlung radiation

“…It is very intriguing, but in the case of the 178m2 Hf isomer triggering by the nuclear excitation through electron transition (NEET), the theoretical estimates differ from the experimental results also by about 9 orders of magnitude [26,27]. At the same time, under some assumptions that look quite realistic, theoretical estimates of the probability of stimulated decay of the 178m2 Hf isomer may differ from experimental results by only one order of magnitude [28].…”
