239CM 243CF A DECAY 14NDS 201411 239CM H TYP=FUL$AUT=E. BROWNE, J. K. TULI$CIT=NDS 122, 293 (2014)$ 239CM2 H CUT=30-Jun-2013$ 239CM D Modified by E. Browne (March 2002). 239CM C QA=7420 KEV, systematic value for 243CF GS decay (2012WA38) 239CM2C suggests that the observed 7170- and 7060-KEV ALPHAS feed 239CM3C levels in 239CM at about 130 and 242 KEV, respectively. 239CM D The ALPHA decay pattern suggested by 1967FI04 is not consistent with 239CM2D systematics of the 1/2[631] band; see, for example, 239PU ALPHA decay 239CM3D and 241CM A DECAY. We expect from these syst ALPHA branches of AP 18% 239CM4D and AP 12% to the 3/2+ and 5/2+ levels of the 1/2[631] band, 239CM5D respectively, and no significant A's at energies above 239CM6D that of the favored 7060A. 239CM CA HF Using R0(239CM)=1.493, average of R0(238CM)=1.490 20 and 239CM2CA R0(240CM)=1.495 12 (1998AK04). 239CM CA E Measurements of 1967FI04 (semi). Other measurement: 1967SI08. 239CM CA IA From 1967FI04. 239CM CL J From adopted levels 243CF P 0.0 (1/2+) 10.7 M 5 7420 SY 239CM N 0.14 AP 239CM L 0.0 (7/2-) 239CM CL Alpha decay to this level was not detected (1967FI04). 239CM L 130 AP ? 239CM A 7170 10 29 AP 4.5 AP ? 239CM CA Not seen by 1967SI08. It may have been obscured in their 239CM2CA spectrum by the presence of the 7.22-MEV ALPHA from 244CF. 239CM L 242 AP(1/2+) 239CM A 7060 10 71 AP 0.70 AP 239CM CA IA 7060A/7171A AP 2.5 is given in 1967FI04. 239CM CA HF$the ALPHA HF is low for J=1/2 (compare HF=2.7 and 2.5 for the 239CM2CA favored transitions in the A DECAY of 239PU and 241CM, respectively) 239CM3CA suggesting that the ALPHA branch for 243CF is <14%, 239CM4CA as estimated in 1967SI08. 239CM CA E 7050 20 is reported in 1967SI08.
