Excited states of 19Mg
We have calculated energies of the first two excited states of 19Mg by using a model that was previously successful for the ground state. Computed excitation energies are 1.12 and 1.54 MeV for (3/2−) and (5/2−), respectively—somewhat in disagreement with values of 1.38 and 2.14 MeV from a recent experiment.

متن کاملPolarizability in Excited States
A linear response of a molecule in excited state to an external electric field is discussed in terms of frequency dependent polarizabilities. Results of accurate calculations of polarizabilities of the hydrogen molecule in its b aL: and B lL/ states are presented. The results are compared with other ab initio and model calculations. It is shown that there is no contribution to the polarizabilit...
متن کاملExcited States in Negative Ions
This thesis covers experimental studies of atomic negative ions with the main goal of increasing our fundamental understanding of these fragile quantum systems. Comparisons of measurements and calculations have been used to increase our understanding of these highly correlated, yet simple, systems. All the described studies in this thesis have investigated the photodetachment process, i.e. when...
متن کاملExcited electronic states of AuF.
We have recorded laser excitation spectra of transitions from the ground X(1)Sigma(+) state of gaseous gold fluoride (AuF) into three excited electronic states in the visible region. We prepared the sample in a dc electric discharge by flowing a dilute mixture of SF(6) in argon through a hollow gold cathode. Two of these electronic states give rise to the previously reported yellow bands of the...
متن کاملEntanglement entropy of excited states
We study the entanglement entropy of a block of contiguous spins in excited states of spin chains. We consider the XY model in a transverse field and the XXZ Heisenberg spin-chain. For the latter, we developed a numerical application of algebraic Bethe Ansatz. We find two main classes of states with logarithmic and extensive behavior in the dimension of the block, characterized by the propertie...
