Cross section measurement of the ¹⁴⁴Sm(α, n)¹⁴⁷Gd reaction for studying the α-nucleus optical potential at astrophysical energies

NUCLEAR REACTIONS ¹⁴⁴Sm(α, n)¹⁴⁷Gd, E=13-20 MeV; measured Eγ Iγ; deduced total σ(E), astrophysical S-factor, constraints on α-nucleus potential. ¹⁴⁴Sm(α, X), E=7.5-20 MeV; analyzed experimental information on σ, deduced contribution of different channels to the σ and S-factor. ¹⁴⁴Sm(α, γ), E=10-13 MeV; calculated S-factor, astrophysical reaction rate using derived optical model parameters. Activation method. Comparison with statistical model calculations, other experimental data and data from REACLIB AND STARLIB. Targets were irradiated at K20 cyclotron accelerator of Atomki and γ-rays from decay was measured by thin HPGe (LEPS).
