Measurement of Spin Correlation Coefficient \({\varvec{C}}_{{\varvec{y}},{\varvec{y}}}\) for Proton-\(^{{\textbf {3}}}\)He Elastic Scattering
We present the measured spin correlation coefficient \(C_{y,y}\) for p-\(^3\)He elastic scattering at 100 MeV at the angles \(\theta _\mathrm{c.m.}=46.9^\circ \)–\(149.2^\circ \) in the center of mass system. The experiment was performed using a 100 MeV polarized proton beam in conjunction with the polarized \(^3\)He target. Proton beams were injected to the target, and scattered protons were detected by using E-\(\Delta E\) detectors which consisted of plastic and NaI(Tl) scintillators. The data are compared with rigorous numerical calculations based on realistic NN potentials as well as with the \(\Delta \)-isobar excitation . The obtained results indicate that the \(C_{y,y}\) expands the knowledge of the nuclear interactions with \(\Delta \)-isobar or those including 3NFs that are masked in nucleon-deuteron elastic scattering.
期刊介绍:
The journal Few-Body Systems presents original research work – experimental, theoretical and computational – investigating the behavior of any classical or quantum system consisting of a small number of well-defined constituent structures. The focus is on the research methods, properties, and results characteristic of few-body systems. Examples of few-body systems range from few-quark states, light nuclear and hadronic systems; few-electron atomic systems and small molecules; and specific systems in condensed matter and surface physics (such as quantum dots and highly correlated trapped systems), up to and including large-scale celestial structures.
Systems for which an equivalent one-body description is available or can be designed, and large systems for which specific many-body methods are needed are outside the scope of the journal.
The journal is devoted to the publication of all aspects of few-body systems research and applications. While concentrating on few-body systems well-suited to rigorous solutions, the journal also encourages interdisciplinary contributions that foster common approaches and insights, introduce and benchmark the use of novel tools (e.g. machine learning) and develop relevant applications (e.g. few-body aspects in quantum technologies).
