Abstract

Abstract Angular distributions of tritons from the 22 Ne(p, t) 20 Ne reaction have been measured at proton bombarding energies of 26.9, 35.1 and 42.4 MeV. All the known energy states up to an excitation energy of 6.72 MeV in 20 Ne were excited, including the unnatural parity 2 - level at 4.97 MeV. DWBA calculations have been made using the finite-range two-nucleon transfer code of Nelson and Macefield. Various wave functions describing 20 Ne and 22 Ne, taken from the work of Arima et al. , Wildenthal et al. , Kuo and Zuker, were used in calculating the spectroscopic amplitudes for transitions to the various final states in 20 Ne. Comparison of the nuclear structure information extracted at the different bombarding energies is emphasized. The sensitivity of the DWBA results to the binding energy of the single- particle states is discussed.
