Abstract：
The excitation functions are determined by activation method and stacked-foil technique for the ⁵⁵Mn(α,n)^58m,gCo,⁵⁵Mn(α,2n)⁵⁷Co^{and 55}Mn(α,α′n)⁵⁴Mn reactions from 10.4 to 26.5MeV.The experimental results are compared with theoretical calculation by exciton model.It is showed that preequilibrium emission reaction mechanism is present in these reactions.
