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.
Journal ArticleDOI
Resonant excitation of the reaction 180 Ta m (γ,γ') 180 Ta
Carl B. Collins,James Carroll,T. W. Sinor,M. J. Byrd,D. G. Richmond,K. N. Taylor,M. Huber,N. Huxel,Peter von Neumann-Cosel,Achim Richter,C. Spieler,W. Ziegler +11 more
Journal ArticleDOI
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.
Journal ArticleDOI
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.
Journal ArticleDOI
Common thresholds and the role of deformations in the photoexcitation of isomers
Carl B. Collins,James Carroll,K. N. Taylor,D. G. Richmond,T. W. Sinor,M. Huber,P. von Neumann-Cosel,Achim Richter,W. Ziegler +8 more
TL;DR: In this paper, the authors reported that the isomers were excited by resonant absorption through isolated intermediate states having integrated cross sections in excess of 10{sup {minus}26} cm{sup 2} keV, i.e., values about 1000 times larger than most activation reactions reported previously although they were comparable to those reported earlier for the depopulating reaction.
