Abstract
Axions with an energy of 8.4 keV emitted in the М1 transition in 169Tm nuclei in the Sun are sought in the A + {{;}^{{169}}}{kern 1pt} {text{Tm}} → 169Tm* → ^{{169}}{text{Tm}} + (gamma ,e) (8.4 keV) reaction of resonant absorption by 169Tm nuclei on the Earth using a {text{T}}{{{text{m}}}_{{text{3}}}}{text{A}}{{{text{l}}}_{{text{5}}}}{{{text{O}}}_{{{text{12}}}}} thulium garnet crystal as a bolometric detector. The flux of monochromatic 8.4‑keV axions has been calculated. New constraints on the axion–nucleon coupling constants have been obtained and, as a result, new upper bounds on the axion mass m_{A}^{{{text{KSVZ}}}} leqslant {text{141}} eV and m_{A}^{{{text{DFSZ}}}} leqslant {text{244}} eV have been obtained at 90% C.L. in the KSVZ and DFSZ models, respectively.
