It is intended to provide a theoretical framework and numerical tools for solving the three body recombination problem and other related processes. This is the situation in which three atoms simultaneously collide, forming an atom and a diatomic molecule, with some of the energy liberated transferred to the rotational and vibrational degrees of freedom of the molecule, the remainder to translational kinetic energy. An important application occurs in Bose-Einstein condensation, where losses from the trap due to three body recombination limit the density achievable in condensates.

旨在为解决三体复合问题及其他相关过程提供理论框架和数值工具。 在这种情况下，三个原子同时碰撞，形成一个原子和一个双原子分子，释放的一些能量转移到分子的旋转和振动自由度，其余能量转移到平动动能。 一个重要的应用发生在玻色-爱因斯坦凝聚中，其中由于三体重组而导致的陷阱损失限制了凝聚态中可达到的密度。
