Abstract:
A computational model based on classical molecular rotation provides insight into the observability of dipole-bound states. The observability is related to the lifetime of the state prior to rotational autodetachment of the electron. The model tracks an ensemble of dipole-bound states. Their motion in space is integrated as a function of time, which provides a means to analyze the lifetimes of the dipole-bound states. The results are generally in good agreement with experimental data. Some exceptions show the limitations of the model but also provide insight into the autodetachment mechanism.

Atomic Nuclei: Types of Nuclear Relaxation
In spin–lattice or longitudinal relaxation, the excited spins exchange energy with the surrounding lattice as they return to the lower energy level. Among several mechanisms that contribute to spin–lattice relaxation, magnetic dipolar interactions are significant. Here, the excited nucleus transfers energy to a nearby...
