摘要:

研究了14.4keV太阳轴子在$^{57}$ Fe靶上的共振吸收。放置在低本底装置内的Si(Li)探测器用于探测14.4 keV核能级去激发中出现的$γ$ -量子:$A+\rm{^{57}Fe} \to \rm{^{57}Fe^{*}} \to \rm{^{57}Fe} + γ$。得到了强子轴子质量的新上限:$m_{A} \leq 151$ eV(90% C. L.)($S$ =0.5,$z$ =0.56)。

英文摘要:

A search for resonant absorbtion of 14.4 keV solar axions by $^{57}$Fe target was performed. The Si(Li) detector placed inside the low-background setup was used to detect the $γ$-quanta appearing in the deexcitation of 14.4 keV nuclear level: $A+\rm{^{57}Fe} \to \rm{^{57}Fe^{*}} \to \rm{^{57}Fe} + γ$. The new upper limit for the hadronic axion mass have been obtained: $m_{A} \leq 151$ eV (90% C.L.) ($S$=0.5, $z$=0.56).
