In a companion paper, new models of waves from ground-based very low frequency transmitters and from lightning were presented. Ray-and-power tracing provided wave amplitudes as well as trajectories and wave normal angles throughout the plasmasphere. Here, these are used to evaluate diffusion of radiation belt electrons. These are combined with recent models of hiss and Coulomb collisions to find lifetimes and particle distributions. Butterfly pitch angle distributions and near-megaelectron volt electrons are produced, confirming the role of energy diffusion. Coulomb energy drag, while often omitted, is also found to be important and should not be neglected.
Relativistic configuration-interaction calculations have been performed for anion binding energies of the entire actinide row using a corelike treatment of the 5f subshell: the same occupancy and universal jls restrictions are applied to the subshell throughout the basis of each neutral and anion calculation. We predict bound 7p attachments to all actinide ground state configurations except Fm, Md, and No. Additional anion bound states are formed by 7p attachment to excited thresholds in Pa and Lr as well as 7s attachments relative to excited open-s thresholds in Th, Pa, U, and Np. Of the 41 bound actinide anion states presented, over half are characterized here for the first time. The most unusual case is Pa − , where these ab initio calculations predict five bound anion states arising from four different configurations.
Relativistic configuration-interaction calculations have been performed for all possible E1, M1, and E2 transitions between bound anion states of La − and Os − . We pay particular attention to E1 transitions in each case that may be of use in laser cooling of these anions. Although the La − transition energy is approximately one-third of the Os − transition, our results indicate that the Einstein A coefficient is nearly two orders of magnitude larger, which would lead to more efficient laser cooling. We have also explored long-lived opposite-parity excited states in Lu − and Lr − which are restricted to M2 decay by selection rules. Finally, in Pr − , we find sufficient mixing between a weakly bound excited 4f 2 5d 2 6s 2 state with a nearby 4f 3 6s 2 6p resonance to result in a lifetime similar to that of the other excited anion states, despite the fact that the dominant configurations of these M1 and E2 transitions differ by two electrons.
Waves from nine major ground-based very low frequency (VLF) transmitters are modeled from their sources to 660 km altitude with a full-wave code, which reliably treats transionospheric attenuation, and then ray-and-power traced throughout the plasmasphere. Lightning-generated whistlers, previously modeled at 660 km altitude, are ray-and-power traced throughout the plasmasphere as well. The resulting profiles of electric and magnetic fields, including wave normal angles, are organized by L value. Two versions of a realistic plasmaspheric density model are used, and ducted as well as nonducted propagation are treated. Results are compared to empirical models based on near-equatorial measurements by Van Allen Probes. A companion paper will evaluate resonant interactions of these waves with radiation belt electrons.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
