“…Because the WF of 9 Li (5) and operators (13), (15), and (17) are written in the form of expansion in Gaussian functions in relative coordinates, the further calculation of the matrix element (1) is not difficult and can be done analytically. An example of such a calculation for the p 6 He system is given in [28]. The experimentally measured differential scattering cross section with which we compare the results obtained here, is determined by the squared absolute value of the respective matrix element:…”

“…is the momentum transfer. The calculation of the matrix elements (1) for 6 He in the α-n-n-model was described in [28]. We will give the brief derivation of the matrix element (1) for the scattering of protons on 9 Li, presented in the −t−2n model.…”

“…We use WFs obtained in the framework of the modern three-body models −n−n (for 6 He) [24], −t−n (for 8 Li) [25], and −t−2n (for 9 Li) [26] with realistic intercluster potentials. The justification for using intercluster potentials to calculate the WFs was given in our previous papers [25][26][27][28]. The static characteristics of the nuclei (rms radii, magnetic and quadrupole moments), the binding energies in the channels, and their comparison with data were shown.…”

Within the framework of the Glauber diffraction theory, the differential cross sections of the elastic р 6 Не, p 8 Li, and p 9 Li scattering were calculated at intermediate energies from 70 to 1000 MeV/nucleon. The use of realistic three-body wave functions −n−n ( 6 He), −t−n ( 8 Li), and −t−2n ( 9 Li), obtained in the framework of modern nuclear models, and the expansion of the Glauber operator into a series of multiple scatterings in a form that is well adapted to the three-body nuclei configuration, allows the calculation of the matrix elements, by taking into account the rescattering from all structure components of the designated nuclei.

Abstract.A calculations of the analyzing power (A y ) of the elastic proton scattering on 6 He and 8 He are presented in the framework of the Glauber multiple diffraction scattering at E = 71 and 1000 MeV/nucleon. The wave functions obtained in the three-body α-n-nmodel for 6 He and the density distribution function in the no-core shell model for 8 He are used. Our calculations qualitatively reproduced the data of A y for p 6 He and p 8 He scattering and compare with the calculations' results in the other approaches.

Small nuclei (A<16) test the limits of optical potential theory, most recently there has been difficulty matching the helium isotopes' analyzing powers at 71 MeV per nucleon. We provide a phenomenological optical potential that has been fit to a variety of experimental proton-nucleus and neutron-nucleus scattering data between A=4 and A=13 with a projectile energy between 65 and 75 MeV; the motivation being the helium isotopes. The resulting potential is dependent only on projectile isospin, neutron, and proton numbers. It fits the analyzing power of 6 He satisfactorily only by including a nontraditional negative surface depth and a spin-orbit force which is significant at a distance larger than traditional models. We offer physical interpretations of our non-traditional results, suggest directions for microscopic calculations, and proffer calculations for future experiments.
