• Excitation functions (EFs) for the reaction ^<141>Pr(α, n)^<144>Pm and ^<141>Pr(α, 2n)^<143>Pm have been measured using ^<141>Pr as a target up to 50MeV α-particle energy. Stacked foil activation technique and γ-ray spectroscopy using 100cm^3 Ge (Li) detector, has been used. Excitation functions are also calculated theoretically using Blann's geometry dependent hybrid (GDH) model code ALICE-91, with and without inclusion of pre-equilibrium particle emission. It has been observed that high-energy tails of the EFs are dominated by pre-equilibrium reaction mechanism. With the accepted set of input parameter, initial exciton number n_0=4(2p+2n+0h), a good qualitative agreement is found. However, quantitative agreement for this magic nucleus ^<141>Pr is also good when theoretical calculations are normalized by a multiple factor of 0.5.
