High-spin structures inPd108: γ-vibrational band and two-quasineutron excitations

摘要: The high-spin structures of the $^{108}\mathrm{Pd}$ nucleus have been studied with $^{100}\mathrm{Mo}(^{11}\mathrm{B},p2n\ensuremath{\gamma})$ reaction at 43 MeV incident energy. $\ensuremath{\gamma}\text{\ensuremath{-}}\ensuremath{\gamma}\text{\ensuremath{-}}t,\ensuremath{\gamma}\text{\ensuremath{-}}\ensuremath{\gamma}$-charged-particle coincidences and directional correlation ratios were measured using SACI-PERERE \ensuremath{\gamma} spectrometer formed by four Compton suppressed HPGe detectors a $4\ensuremath{\pi}$ charged-particle ancillary detector system. Recent results for \ensuremath{\gamma}-vibrational band $\ensuremath{\nu}{h}_{11/2}\ensuremath{\bigotimes}\ensuremath{\nu}({g}_{7/2},{d}_{5/2})$ negative parity confirmed complemented. A new tentatively based on second lowest $(\ensuremath{\nu}{h}_{11/2})$ excitation has observed.
