Re: Nd-144 -Reply

David,

The half  life of Nd-144 was determined in 1954 but there seems to have been
some disagreement about the value (2 E 15 vs 5 E 15 years). Essentially the
present value was included in the 1967 edition of  "Table of Isotopes," by Lederer,
Hollander and Perlman.  Also it was in the 1968 edition of the KAPL/GE "Chart of
the Nuclides," by Holden and Walker.
