| Abstract | Radiative lifetimes of three elements of the nitrogen group have been
experimentally investigated at the Double ElectroStatic Ion Ring Experiment
(DESIREE) facility at Stockholm University. The experiments were performed
through selective laser photodetachment of excited states of P$^-$, As$^-$ and
Sb$^-$ ions stored in a cryogenic storage ring. The experimental results were
compared with theoretically predicted lifetimes, yielding a mixture of very
good agreements in some cases and large discrepancies in others. These results
are part of our efforts to map out the lifetimes of all excited states in
negative ions. This data can be used to benchmark atomic theories, in
particularly with respect to the degree of electron correlation that is
incorporated in various theoretical models. |
