Scientific paper

The statistical Hauser-Feshbach (HF) model performs poorly in calculating the (γ, α) rates that are critical to the p process. Experimental work on elastic scattering of the tellurium isotopic chain [A. Palumbo (unpublished)] provided a new parametrization of the α-optical potential and consequently new HF calculations of the (α,x) cross sections on 120-130Te. However, reliable experimental cross sections of these isotopes have not been measured at energies relevant to the p process. To test the reliability of the HF calculations, we measured the (α,n) cross sections on 120Te, one of the p nuclei, using the activation technique. The results are compared with the HF model calculations.
