Photoexcitation of nuclear isomers by (γ,γ ’ ) reactions
James Carroll,M. J. Byrd,D. G. Richmond,T. W. Sinor,K. N. Taylor,W. L. Hodge,Y. Paiss,C. D. Eberhard,J. A. Anderson,Carl B. Collins,E. C. Scarbrough,Peter P. Antich,F. J. Agee,David P. Davis,G. A. Huttlin,K. G. Kerris,Marc Litz,D.A. Whittaker +17 more
TL;DR: In this paper, photoexcitation of the isomers of 19 nuclides was examined in four accelerators were used as sources of bremsstrahlung to expose the samples and end-point energies covered the range from 0.5 to 11 MeV.

Resonant photoexcitation of isomers. 115Inm as a test case
P. von Neumann-Cosel,Achim Richter,C. Spieler,W. Ziegler,James Carroll,T. W. Sinor,D. G. Richmond,K. N. Taylor,Carl B. Collins,Kristiaan Heyde +9 more
TL;DR: In this article, large integrated cross sections for photoexcitation of 115Inm have been detected around Ex=3MeV and it is shown that the g.s. transition strength is largely confined to the same energy region and the intermediate excited states are identified.

Structure of intermediate states in the photoexcitation of the 89Y isomer
M. Huber,P. von Neumann-Cosel,Achim Richter,C. Schlegel,R. Schulz,James Carroll,K. N. Taylor,D. G. Richmond,T. W. Sinor,Carl B. Collins,V. Yu. Ponomarev +10 more
TL;DR: In this article, a measurement of the 89Ym excitation function for bremsstrahlung endpoint energies E0 = 2−5 MeV and in a nuclear-resonance-fluorescence experiment with E 0 = 5 MeV were compared to a quasiparticle-phonon calculation.

Intermediate structure in the photoexcitation of 77Sem, 79Brm, and 137Bam.

TL;DR: Intermediate states in $^{77}\mathrm{Se}$ displayed very large strengths compared to other isomers in the same mass region, providing further support for the correlation between integrated cross sections and ground state deformations recently discovered in the A=160--200 mass region.
