69CU c 2001Fr21,1998Fr15: {+69}Ni produced from 30 MeV proton induced fission
69CU2c reaction on {+238}U. Extracted selectively by resonant laser
69CU3c ionization and mass separator (LIGIS-LISOL) facility at Leuven.
69CU4c Measured |b|g and |g|g coincidence spectra with high purity Ge
69CU4c detectors and plastic scintillators. Measured T{-1/2} from timing of
69CU5c |b delayed |g intensity.
69CU c 1999Pr10,1998PrZY: {+69}Ni produced by fragmentation of 70
69CU2c MeV/nucleon {+76}Ge beam on Be target using the A1200 separator at
69CU3c NSCL, MSU. |b delay |g measured with two thin plastic scintillators
69CU4c and two large-volume Ge detectors.
69CU c 1988Bo06,1987BoZW: {+69}Ni produced by irradiation of thick W target
69CU2c with 11.5 MeV/u {+76}Ge beam followed by on-line mass separation;
69CU3c measured E|g, I|g, |b|g, |g|g coincidences using 300|mm Si detector,
69CU4c NE102A plastic scintillator, 33 % efficiency Ge and 4|p lucite
69CU5c detectors.
69CU c 1985Bo49: {+69}Ni produced and identified in W({+76}Ge,X)
69CU2c reaction at 11.4 MeV/nucleon followed by mass separation at GSI
69CU3c facility. Measured |g, |b, |b|g coin on the decay of 205|g, 680|g and
69CU4c 1213|g, and isotopic half-life using Ge, Si detectors and plastic
69CU5c scintillators.
69CU c 1985Bo49: {+69}Ni produced by irradiation of W target with 11.4 MeV/u
69CU2c {+76}Ge beam. On-line mass separation; measured E|g, I|g, T{-1/2},
69CU3c |b|g coincidences.
69CU c 1985Ru05: {+69}Ni produced by irradiation of W target with
69CU2c 11.5 MeV/nucleon {+76}Se beam followed by on-line mass separation.
69CU3c Measured E|g, I|g, T{-1/2}, |b|g coincidences using 4|p plastic |b
69CU4c and Ge detectors.
69CU cB LOGFT$Values in comments are from 2001Fr21; authors give lower limits
69CU2cB to account for possible unobserved feeding from higher levels
69CU cG E,RI$From 2001Fr21, except as noted. Due to limited
69CU2cG statistics and decreasing detector efficiency for high energy
69CU3cG transitions, |g's to g.s. from levels above 2 MeV may have be missed
