The journal Few-Body Systems presents original research work, both experimental and theoretical, investigating the behavior of few-body systems. These are understood as 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 problems include light nuclear systems (few-nucleon bound and scattering states), small molecules as well as light atoms (few-electron systems in external fields), specific systems in condensed matter and surface physics (quantum dots); however, also systems as large as celestial systems and as small as elementary particles.The journal is interdisciplinary, offering research in particle, nuclear, atomic, molecular, and condensed-matter physics, as well as from astrophysics, astronomy, mathematics, and chemistry.The journal also publishes papers in the form of letters, rapid communications, comments, and reviews or progress reports.

《少體系統》期刊發表了一些原創的研究工作，包括實驗和理論研究，研究了少體系統的行為。它們被理解為由少量定義良好的組成結構組成。重點研究了少體系統的研究方法、性能和結果特性。少體問題的例子包括輕核系統(少核子束縛態和散射態)、小分子以及輕原子(外場中的少電子系統)、凝聚態和表面物理中的特定系統(量子點);然而，也有像天體系統那樣大，像基本粒子那樣小的系統。該雜志是跨學科的，提供粒子、核、原子、分子和凝聚態物理的研究，以及天體物理學、天文學、數學和化學的研究。該雜志還以信件、快速通訊、評論、評論或進度報告的形式發表論文。
