Experimental Parameters

The benchmarking experimental procedure in IBA (Ion Beam Analysis) is carefully designed in order to validate evaluated and experimental differential cross–section datasets of charged particles via the acquisition of EBS and NRA spectra from thick targets of known composition, followed by their simulations. In the present work, such benchmarking measurements have been performed at the laboratory of the Institute for Nuclear and Particle Physics “Demokritos”, for the elastic scattering of protons on natSi in the energy range of 1.1 – 3.5 MeV at four backward angles, at 140o, 150o, 160o and 170o. In addition, measurements were performed for the elastic scattering of deuterons on 16O in the energy range of 1.1 – 1.7 MeV at four backward angles, at 140o, 150o, 165o and 170o. More specifically, a thick non–polished Si target with Au evaporated on top and a Nb2O5 tablet were used. The spectra acquired were compared with simulated ones using the SIMNRA program along with the evaluated differential cross-section datasets from IBANDL. All the experimental parameters were thoroughly investigated. The obtained results, the observed discrepancies and the encountered problems during the benchmarking process are discussed and analyzed.

Differential cross sections for elastic scattering and ionization in positron–argon collisions as a function of energy (40–150 eV) are reported at 60°. Of particular interest is the energy range 55–60 eV, where earlier measurements by the Detroit group found a drop in the elastic-scattering cross section of a factor of 2. This structure has been tentatively attributed to a cross channel-coupling effect with an open inelastic-scattering channel, most likely ionization. Our results indicate that ionization remains an important channel over the same energy range and only begins to decrease at an energy above 60 eV.

Based on the (spin-independent) Sugar–Blanckenbecler eikonal expansion for the T-matrix, we parametrize the (spin-dependent) NN amplitude (SNN) which successfully describes the pp and pn elastic scattering observables at ~ 1 GeV up to the available momentum transfers. Using SNN, we calculate the differential cross-section, polarization, and spin-rotation function of ~ 1 GeV protons on 4 He within the framework of the Glauber model. The analysis also includes the phase variation in the NN amplitude. It is found that the use of SNN, in comparision with the usually parametrized one-term amplitude, improves the agreement with the experimental data. The introduction of a global phase variation provides only a slight improvement over the results with a constant phase. However, if we allow different phases in the central- and spin-dependent parts of the NN amplitude, the agreement with the polarization data improves further without affecting the differential cross-section results.

In order to obtain information about the levels of even spin and parity of 8 Be at energies above 11 MeV, the differential cross-section for the α-particle-helium elastic scattering has been measured at a series of beam energies from 23·1 to 38·4 MeV, for many c.m.s. angles between 30 and 90°. Phase shifts up to L = 8 have been calculated for each energy. Combining these results with previous figures for lower energies, the phase shifts δ 0 , δ 2 and δ 4 are thus known as functions of incident energy from 0·15 MeV to 38·4 MeV. The behaviour of the phase shift δ 4 confirms the existence of a previously suggested level with I = 4 at an excitation energy of about 11·4 MeV in 8 Be. The phase shifts δ 6 and δ 8 are small, as expected if the rotational series of levels in 8 Be term inates with I = 4.
