66NI 66CO B- DECAY 2000MU10,1988BO06 10NDS 201004 66NI H TYP=FUL$AUT=E. BROWNE, J. K. TULI$CIT=NDS 111, 1093 (2010)$ 66NI2 H CUT=3-Mar-2009$ 66NI D Modified by E. Browne (April 24, 2009) 66NI C 2000MU10: 66CO produced by irradiation of 238U foils with 30-MeV 66NI2C protons. 66CO was separated from other recoiling fission products 66NI3C using a laser-ionization isotope-separation method. These isotopes 66NI4C were then mass separated. Measured BG COIN and GG COIN. Detectors: 66NI5C Ge hyperpure and plastic scintillators. 66NI C 1998BO06: 66CO produced by irradiation of a thick W target with a 66NI2C 11.5-MeV/^A 76GE beam. On-line mass separation. Measured EG, RI, 66NI3C BG COIN, GG COIN. Detectors: hyperpure Ge and plastic scintillators. 66NI4C 1988BO06 reported a 471.3 keV 6 G ray with RI=23 4. 2000MU10 searched 66NI5C for this G ray but could not find it. Thus, its existence remains 66NI6C to be confirmed, and thus there is no support for levels at 2916 66NI7C and 2445 keV associated with this transition. 66NI C Other measurement: 1985Bo49. 66CO P 0.0 (3+) 0.20 S 2 9.89E+3 25 66NI N 1.00 1.0 66NI CN NR From IG(1426)= 100 % 4. Measured B- spectrum. No B- 66NI2CN population to the ground state of 66NI was observed (1988BO06). 66NI PN 4 66NI L 0.0 0+ 54.6 H 3 66NI CL T From Adopted Levels, Gammas. 66NI L 1425.92 20 2+ 66NI CL J From Adopted Levels, Gammas. 66NI B 22 5 5.0 66NIS B EAV=3941 122 66NI G 1425.9 2 100 4 66NI CG Other value: EG=1424.8 keV 10, RI=100 10 (1988BO06). 66NI L 2672.0 3 (3+) 66NI CL J From log ft= 4.2 and shell-model arguments. 66NI B 69 5 4.2 66NIS B EAV=3333 122 66NI G 1246.1 2 69 5 66NI CG Other value: EG=1246.0 keV 9, RI=98 11 (1988BO06). 66NI L 3230.6 3 2+ 66NI CL J From log ft= 4.9 and shell-model arguments. 66NI B 9 2 4.9 66NIS B EAV=3061 122 66NI G 1804.7 2 9 2
