50K c 2010Da06, 1999DaZQ: Ni({+86}Kr,X) E=60.3 MeV/nucleon. Measured
50K 2c delayed E|g, I|g following decay of isomeric states using LISE
50K 3c spectrometer at GANIL. Deduced J, |p, T{-1/2}, multipolarities
50K c 2009Cr03: {+9}Be({+76}Ge,X) E=130 MeV/nucleon. Fragments were separated
50K 2c using A1900 FRS. Measured prompt |g rays using SeGa array of
50K 3c Ge detectors. Three |g rays at 43.0, 128.4 and 172.1 keV were
50K 4c reported from the decay of the isomer
50K c 2012Ka36: {+50}K isomer produced in {+9}Be({+238}U,F),E=345 MeV/nucleon
50K 2c provided by the RIBF accelerator complex at RIKEN facility. Fission
50K 3c fragments were separated and analyzed by BigRIPS separator, transported
50K 4c to focal plane of ZeroDegree spectrometer and finally implanted in an
50K 5c aluminum stopper. Particle identification was achieved by |DE-TOF-B|r
50K 6c method. Delayed gamma rays from microsecond isomers were detected by
50K 7c three clover-type HPGe detectors. Measured E|g, I|g, |g|g-coin, isomer
50K 8c half-life.
50K cG E,RI$ From 1999DaZQ, unless otherwise noted.
50K cG M(D)$E2 suggested by 1999DaZQ, in contrast to M1 or E1, based on
50K 2cG Weisskopf estimates for E2, M1 and E1 transitions.
50K cG E(A)$Weak |g-ray
50K cG E(E)$Ordering of the 127-44 and 101-70 |g cascades can be reversed
50K 2cG as in 2009Cr03 for the former
