Determination of stellar shape in microlensing event MOA 2002-BLG-33
N. J. Rattenbury, F. Abe, D. P. Bennett +30
We report a measurement of the shape of the source star in microlensing event MOA 2002-BLG-33. The lens for this event was a close binary whose centre-of-mass passed almost directl…
Simplified diagrammatic expansion for effective operator
Chang-Kui Duan, Yungui Gong, Hui-Ning Dong +1
For a quantum many-body problem, effective Hamiltonians that give exact eigenvalues in reduced model space usually have different expressions, diagrams and evaluation rules from ef…
Conservation of connectivity of model-space effective interactions under a class of similarity transformation
Chang-Kui Duan, Yungui Gong, Hui-Ning Dong +1
Effective interaction operators usually act on a restricted model space and give the same energies (for Hamiltonian) and matrix elements (for transition operators etc.) as those of…
Calculation of single-beam two-photon absorption rate of lanthanides: effective operator method and perturbative expansion
Chang-Kui Duan, Gang Ruan, Michael F. Reid
Perturbative contributions to single-beam two-photon transition rates may be divided into two types. The first, involving low-energy intermediate states, require a high-order pertu…
The unusual temperature dependence of the Eu fluorescence lifetime in CaF crystals
C. K. Duan, A. Mejerink, R. J. Reeves +1
Fluorescence lifetimes of Eu doped in CaF are measured at various temperatures between 4K and 450K. The lifetime increases with between 100K and 300K, in contrast to the…
General calculation of transition rates for rare-earth ions using many-body perturbation theory
Chang-Kui Duan, Michael F. Reid
The transition rates for rare-earth ions in crystals can be calculated with an effective transition operator acting between model and states calculated…
