Abstract

Excitation functions taken at 100 keV steps and extending from 17 MeV to 26.5 MeV have been obtained for the elastic scattering of protons by ¹⁴N and also the inelastic scattering exciting the levels at 2.31 MeV and 3.95 MeV. The excitation functions were obtained at c.m. angles of 90°, 125° and 160°. No evidence for resonance behavior was seen in the energy region covered. Angular distributions for the elastic, 2.31 MeV and 3.95 MeV levels were obtained at 18, 21, 23 and 26 MeV bombarding energy. The elastic scattering was analyzed with the optical model. The transition from the J^π; T = 1⁺; 0 ground state to the J^π; T = 0⁺; 1 level was analyzed using Visscher-Ferrell wave functions and a central plus tensor interaction. The strength of the tensor interaction was deduced. Using a range parameter α = 0.71 fm⁻¹ and a regularizing parameter β = 2 fm⁻¹, V_T was found to be 5.5, 5.6, 5.0 and 4.2 MeV at 18, 21, 23 and 26 MeV bombarding energy.

Relative biological effectiveness measurements of low energy proton and lithium beams on tumor cells
2002, Nuclear Instruments and Methods in Physics Research, Section B: Beam Interactions with Materials and Atoms
External proton and $^{6,7}$ Li beams, of energies around 24 and 48 MeV respectively, were produced and characterized dosimetrically at the Tandem accelerator TANDAR in Buenos Aires and used for radiobiology studies on tumor and normal cell cultures. The beam monitoring instrumentation of a dedicated beam line is discussed. Relative biological effectiveness (RBE) values (at 10% survival) have been measured as functions of projectile energy (0–21 MeV) for protons and $^{6,7}$ Li ions for different tumor (PDV, PDVC57) and reference cell lines (V79). The RBE values for these cell lines have been determined here for the first time but are similar to those reported in the literature for other cell lines.
Importance of the sequential two-step transfer process in A ΔS = 1 and ΔT = 1 inelastic transition of the 14N(p, p') 14N reaction
1982, Nuclear Physics, Section A
Differential cross sections and vector analyzing powers for ¹⁴N(p, p′) and ¹⁴N(p′, d) reactions have been measured at E_p = 21.0 MeV to elucidate the reaction mechanism and the effective interaction for the ΔS = ΔT = 1 transition in the ¹⁴N(p, p′)¹⁴N(2.31 MeV) reaction. The data are analyzed in terms of the finite-range distorted-wave Born approximation (DWBA) which includes direct, knock-on exchange and (p, d) (d, p′) two-step processes. Shell-model wave functions of Cohen and Kurath are used. The data for the first excited state are reasonably well explained by including a two-step process in the calculations. The two-step process explains half of the experimental intensity. Moreover the vector analyzing power cannot be explained without introducing this two-step process. The vector analyzing power of protons leading to the second excited state in ¹⁴N is better explained by introducing a macroscopic calculation. The data for the ¹⁴N(p, d) ¹³N (g.s.) reaction are well described by a DWBA calculation using a modified deuteron optical potential. The knock-on exchange contribution is relatively small. The importance of this two-step process for ΔS = ΔT = 1 transitions up to 40 MeV is discussed.
Compound-nucleus effects in nucleon depolarization

Charged particle reaction studies on 14C
1975, Nuclear Physics, Section A
We have measured the reactions ¹⁴C(p, d), (d, d′) and (d, p) for E_p = 27 MeV and E_p = 17 MeV. The (d, d′) and (d, p) reactions were studied between θ_lab = 15° and 85°; the (p, d) reaction between θ_lab = 5° and 40°. The ¹⁴C deformation parameters were deduced from the deuteron inelastic scattering and found to agree with deformations measured in nearby doubly even nuclei. The spectroscopic factors deduced from the (p, d) reaction allowed a ¹⁴C ground-state wave function to be deduced which compares faborably with a theoretically deduced wave function. The (p, d) and (d, p) spectroscopic factors are consistent. The implications of our ¹⁴C ground-state wave function regarding the problem of the ¹⁴C hindered beta decay are discussed.
Square graphs in direct nuclear reactions at moderate energies
1974, Annals of Physics
The present work contains the analysis of various reactions proceeding at relatively small projectile energies (∼ 10 MeV) for which a mechanism described by the square diagram may be regarded as a dominant one. It is shown that such a mechanism may be realized both in reactions in which one or several nucleons are transferred and in reactions of nucleon or deutron inelastic scattering. Also, such an interesting property of the above diagrams is discussed as the extremely well pronounced forwardness of the angular distributions for the processes of inelastic scattering. Various variants of the theory are examined (DWBA, oscillator approximation, etc.). Formal properties of the square diagrams are also studied such as the dependence of differential cross section shape on the value of total orbital momentum transferred and the approximation on an energy surface for its calculation.
