Search for Resonant Absorption of Solar Axions Emitted in M1 Transition in ${}^{57}$Fe Nuclei

Abstract

A search for resonant absorbtion of 14.4 keV solar axions by ${}^{57}$Fe target was performed. The Si(Li) detector placed inside the low-background setup was used to detect the $\gamma$-quanta appearing in the deexcitation of 14.4 keV nuclear level: $A+{}^{57}\mathrm{Fe}\to {}^{57}\mathrm{F}{\mathrm{e}}^{\ast }\to {}^{57}\mathrm{Fe}+\gamma$. The new upper limit for the hadronic axion mass have been obtained: $m_A\le 151$ eV (90% C.L.) ($S$=0.5, $z$=0.56).
