144ND C  T1/2(148SM)=8E+15 Y 2 was measured by 1968KO06, 7E+15 Y 3 by 1970GU14.
144ND2C  The R0 parameter is calculated as 1.575 15 for T1/2=8E+15 Y
144ND3C  and 1.58 3 for T1/2=7E+15 Y 3. A similar trend to the R0
144ND4C  values of Er isotopes suggests R0(144ND)=1.55 3.
144ND C  T1/2(148SM)=12E+15 Y 5 is obtained for R0=1.55 3 from
144ND2C  calculations of R0's as a function of half-lives. Although within
144ND3C  their uncertainties they agree with each other, the R0 value
144ND4C  calculated by using the measured T1/2 of 1968KO06 fits the local trend
144ND5C  better.

144ND CA HF        R0(144ND)=1.57 2 is the rounded-down value of R0 obtained by
144ND2CA using T1/2(148SM)=8E+15 Y in calculations and by requiring
144ND3CA HF(1932.3A)=1.0.

144ND CA E         calculated from QA(148SM)=1986.0 12. EA=1.96 MEV 2
144ND2CA (1970GU14). Other measurement:
144ND3CA EA=1.90 MEV 5 (1968KO06).
144ND CA IA        only one ALPHA group was observed. An upper limit of
144ND2CA 1.2E-15 per 100 A DECAYS is calculated for an unobserved ALPHA
144ND3CA transition to the 2+ state at 696.513 KEV by requiring its hindrance
144ND4CA factor to be greater than 1.0.
