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(tǒng)》期刊發(fā)表了一些原創(chuàng)的研究工作，包括實驗和理論研究，研究了少體系統(tǒng)的行為。它們被理解為由少量定義良好的組成結(jié)構(gòu)組成。重點研究了少體系統(tǒng)的研究方法、性能和結(jié)果特性。少體問題的例子包括輕核系統(tǒng)(少核子束縛態(tài)和散射態(tài))、小分子以及輕原子(外場中的少電子系統(tǒng))、凝聚態(tài)和表面物理中的特定系統(tǒng)(量子點);然而，也有像天體系統(tǒng)那樣大，像基本粒子那樣小的系統(tǒng)。該雜志是跨學(xué)科的，提供粒子、核、原子、分子和凝聚態(tài)物理的研究，以及天體物理學(xué)、天文學(xué)、數(shù)學(xué)和化學(xué)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(fā)表論文。
