Axions of energy 14.4 keV that originated from the M1 transition in {sup 57}Fe nuclei in the Sun were sought by using the resonance-absorption reaction A+{sup 57}Fe {yields} {sup 57}Fe* {yields} {sup 57}Fe+{gamma} (14.4 keV). Asectioned Si(Li) detector arranged in a low-background facility was used to record photons from this reaction. This resulted in setting a new limit on the axion couplings to nucleons, vertical bar -1.19g{sub AN}{sup 0} + g{sub AN}{sup 3} vertical bar {<=} 3.0 Multiplication-Sign 10{sup -6}. Within the hadronic-axion model, the respective constraint on the axion mass is m{sub A} {<=} 145 eV (at a 95% C.L.).
