Abstract
The data analysis is in progress with the aim to determine the differential cross sections for the \(^{1}\)H(d, pp)n breakup reaction at four deuteron beam energies between 300 and 400 MeV. The data have been measured with the use of the WASA detector at COSY-Jülich. This work is focused on the beam energy of 380 MeV (190 MeV/nucleon). Set of proton-proton coincidences registered at the Forward Detector is analysed on a dense grid of kinematic variables. The one of the main steps of the analysis is efficiency study. Their impact on the final accuracy of the result is discussed.
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).
