These results establish the first laboratory constraints on the axion-nucleon coupling for axion masses below $10^{-22}$ eV. For $10^{-22} \\leq m_a \\leq 5 \\times 10^{-21}$ eV, the results improve upon previous laboratory limits by more than 3 orders of magnitude, exceeding for the first time the astrophysical limits from supernova SN1987A cooling.
