我们在太阳核中寻找了57 Fe核发射的14.4keV单色轴子。利用~（57）Fe核的共振吸收，没有观察到与轴子有关的证据，并在95% C. L.处得到了轴子质量的上限ma<216 eV。这个极限比以前的类似实验严格3.4倍，并且除了SN 1987 A的论点之外，是纯粹从轴子-核子耦合获得的最严格的实验极限。
We have searched for 14.4 keV monochromatic axions which could be emitted from57Fe nuclei in the solar core. Using the resonant absorption of57Fe nuclei, no evidence related to the axions is observed, and upper limit on axion mass of ma<216 eV is obtained at 95% C.L. This limit is factor 3.4 more stringent than the previous similar experiment, and, except for the SN1987A arguments, the most stringent experimental limit purely obtained from axion–nucleon couplings.
