 40CA d  activity measurements: 2009ReZZ (activity in marine sediments),
 40CA2d  2009SiZZ (soil natural activities)

 40CA5c  1948Ev09, 1947Gl07. This list is not complete, see 1978LeZA for
 40CA6c  several other references that are not present in NSR database.
 40CA c  The decay scheme, which includes the |b{+-} decay to the
 40CA2c  ground state of {+40}Ca and two levels in {+40}Ar, is complete since
 40CA3c  these are the only levels in the daughter nuclides below the
 40CA4c  respective decay energies.
 40CA d            Decay data evaluated by R. G. Helmer, September 1996 with
 40CA2d  minor editing in July 1998. This
 40CA3d  evaluation was done under the collaboration including evaluator
 40CA4d  from Laboratoire Primaire des Rayonnments Ionisants (LPRI) in
 40CA5d  France; Physikalisch-Technische Bundesanstalt (PTB) in Germany;
 40CA6d  Imperial College in the United Kingdom; and Brookhaven National
 40CA7d  Laboratory (BNL), Lawrence Berkeley National Laboratory (LBNL),
 40CA8d  and Idaho National Engineering and Environmental Laboratory
 40CA9d  (INEEL) in the United
 40CA0d  States. This evaluation was reviewed and accepted by
 40CAAd  evaluator in this collaboration.

 40CA2cN I|g(1460|g)/I|b{+-}=0.1195 {I14}, which is equal to

 40CA4cN {I14} from evaluation of 1973EnVA, and
 40CA5cN |e/|b{++}({+40}K to {+40}Ar g.s.)=45.2 {I14} (3U theory), with
 40CA6cN all |b{++}) decay proceeding to {+40}Ar ground state. Previously
 40CA7cN evaluated value by 1999BeZQ,1999BeZS is 0.8914 {I13} based on the
 40CA8cN estimation of |e/|b{++}=200 {I100} for the unique 3rd forbidden branch
 40CA9cN to the {+40}Ar ground state.
