New insights into triaxiality and shape coexistence from odd-mass $^{109}$Rh
2018
International audience; Rapid shape evolutions near A=100 are now the focus of much attention in nuclear science. Much of the recent work has been centered on isotopes with Z≤40, where the shapes are observed to transition between near-spherical to highly deformed with only a single pair of neutrons added. At higher Z, the shape transitions become more gradual as triaxiality sets in, yet the coexistence of varying shapes continues to play an important role in the low-energy nuclear structure, particularly in the odd-Z isotopes. This work aims to characterize competing shapes in the triaxial region between Zr and Sn isotopes using ultrafast timing techniques to measure lifetimes of excited s…
Neutron configurations inPd113
2014
Excited states in $^{113}\mathrm{Pd}$, populated in ${\ensuremath{\beta}}^{\ensuremath{-}}$ decay of $^{113}\mathrm{Rh}$ and in spontaneous fission of $^{248}\mathrm{Cm}$ and $^{252}\mathrm{Cf}$, have been studied by means of $\ensuremath{\gamma}$ spectroscopy at the IGISOL facility of Jyv\"askyl\"a University and using large arrays of Ge detectors (Eurogam2 and Gammasphere, respectively). The position of the ${11/2}^{\ensuremath{-}}$ yrast excitation in $^{113}\mathrm{Pd}$, proposed recently at 166.1 keV by other authors, has been corrected to 98.9 keV. The decay of this level has been discussed to explain the observed transition intensities. The ${7/2}^{\ensuremath{-}}$ member of the yras…
