Measurement and analysis of alpha particle induced reactions on praseodymium

Excitation functions (EFs) for the reaction 141Pr(α,n)144Pm and 141Pr(α,2n)143Pm have been measured using 141Pr as a target up to 50 MeV α-particle energy. Stacked foil activation technique and γ-ray spectroscopy using 100 cm3 Ge (Li) detector, has been used. Excitation functions are also calculated...

Description
Summary:Excitation functions (EFs) for the reaction 141Pr(α,n)144Pm and 141Pr(α,2n)143Pm have been measured using 141Pr as a target up to 50 MeV α-particle energy. Stacked foil activation technique and γ-ray spectroscopy using 100 cm3 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 n0=4 (2p+2n+0h), a good qualitative agreement is found. However, quantitative agreement for this magic nucleus 141Pr is also good when theoretical calculations are normalized by a multiple factor of 0.5.
