Gamma Decay of the ^{154}Sm Isovector Giant Dipole Resonance: Smekal-Raman Scattering as a Novel Probe of Nuclear Ground-State Deformation.

Journal Article Physical review letters · January 2025 γ decays of the isovector giant dipole resonance (IVGDR) of the deformed nucleus ^{154}Sm were measured using 2_{1}^{+}-Smekal-Raman and elastic scattering of linearly polarized, quasimonochromatic photon beams. The two scattering processes were disentangl ... Full text Cite

Transition width of the Jπ=1- two-phonon state of Sr 88

Journal Article Physical Review C · August 1, 2024 The ground-state decay width of the two-phonon Jπ=1-, 4742 keV state of Sr88 has been determined with the relative self-absorption method combined with a monoenergetic photon beam. This width is important to determine the decay transition strengths into th ... Full text Cite

Characterization of 235U, 238U and 239Pu fission ionization chamber foils by α and γ-ray spectrometry

Journal Article Nuclear Instruments and Methods in Physics Research, Section A: Accelerators, Spectrometers, Detectors and Associated Equipment · June 1, 2024 The masses of thin, electroplated deposits of 235U, 238U and 239Pu on titanium backings have been determined to better than 1.3% precision by employing three complementary measurement techniques: α spectrometry, 2π gas counting, and γ-ray spectrometry. A d ... Full text Cite
