A new experimental scheme is proposed to search for almost monochromat
ic solar axions, whose existence has not been discussed heretofore. Th
e axions would be produced when thermally excited Fe-57 in the Sun rel
axes to its ground state and could be detected via resonant excitation
of the same nuclide in a laboratory. A detailed calculation shows tha
t the rate of the excitation is up to order I event/day kg Fe-57. The
excitation can be detected efficiently using bolometric techniques.
