Excitation functions for the reactions55Mn(α, n)58Co,55Mn(α, 2n)57Co,55Mn(α,3n)56Co,55Mn(α,4n)55Co,55Mn(α, nα)54Mn+55Mn(α, 3n2p)54Mn,55Mn(α,3nα)52Mn have been measured in the energy range ≈(10÷60) MeV using stacked foil technique. Irradiations have been performed for two separate stacks with the alpha-particle beams of (59.96±0.54) MeV and (29.93±0.54) MeV, respectively. Ge(Li) gamma-ray spectroscopy has been used for analysis of irradiated samples. Excitation functions have also been calculated theoretically using two different computer codes,viz. ALICE/LIVERMORE-82 and ACT. Calculations using code ACT with the inclusion of pre-compound contribution based on exciton model agree well with the measured excitation functions, particularly in the high-energy region. Analysis of the data has indicated the preference for first chance neutron emission and interesting trend in pre-equilibrium fraction with energy has been observed.
