Tuli$ 142ND2 H CIT=NDS 112, 1949 (2011)$CUT=1-Jun-2010$ 142ND C Evaluation from 1998Ak04 142ND C T1/2(146SM)=10.3E+7 Y 5, adopted half-life of 1990Pe06, is used in 142ND2C calculations here. A recalibrated value is the weighted average 142ND3C of the following measured half-lives: 10.26E+7 Y 48 (1966Fr11), 142ND4C 10.31E+7 Y 45 (1987Me08). Other measured half-lives: 5E+7 Y (1953Du21), 142ND5C 8.5E+7 Y 12 (1963Fr06), 7.4E+7 Y 15 (1964Nu02). 142ND C 142ND C %A=100. 146SM is BETA stable. 142ND C 142ND C QA(146SM)=2528 3 is the recommended value of 2011AuZZ 142ND CA IA ALPHA intensity per 100 A DECAYS. 142ND CA HF R0(142ND)=1.569 8 is computed from HF(2460A)=1.0. 146SM P 0.0 0+ 10.3E+7 Y 5 2528 3 142ND N 1.0 142ND L 0.0 0+ 142ND A 2460 3 100 1.0 142ND CA EA=2455 4 was measured by 1987Me08 and recommended by 142ND2CA 1991Ry01; QA=2528 3 of 2011AuZZ yields EA=2493 3. 142ND CA IA the first 2+ in 142ND is at 1575.83 KEV. 142ND2CA With the available QA(146SM)=2528 3, a 926-KEV ALPHA to the 2+ state 142ND3CA is not expected.
