Search for axioelectric effect of 5.5 MeV solar axions using BGO detectors

A search for axioelectric absorption of solar axions produced in the reactions has been performed with a BGO detector placed in a low-background setup. A model-independent limit on an axion-nucleon and axion–electron coupling constant has been obtained: for 90 % confidence level. The constrains of t...

Zusammenfassung:	A search for axioelectric absorption of solar axions produced in the reactions has been performed with a BGO detector placed in a low-background setup. A model-independent limit on an axion-nucleon and axion–electron coupling constant has been obtained: for 90 % confidence level. The constrains of the axion–electron coupling have been obtained for hadronic axion with masses in (0.1–1) MeV range: \| g Ae \|≤(1.4–9.7)×10 −7 .
