CN NR Based on the assumption that IB- to GS is negligible
1C Natural HG(N,P) E(N)=14 MEV; gammas GE(LI), GG, G(T) (1984Cr01)
CG From 1984Cr01, assignment to 204AU based on T1/2 and on
2CG GG-coin; other: 1972Pa06. For EG<400 sensitivity was reduced by shield.
CG E(D) Assigned to both 204AU and 202AU (1984Cr01)
CG M From adopted G's
1C HG(N,P) E(N)=14-15 MEV; gammas GE(LI), GG-coin scin-GE(LI), BG-coin
2C scin-GE(LI). Earlier assignment by 1967Wa23 of T1/2=4 S, to 204AU, is
3C not confirmed by 1972Pa06.
CG All intense gammas are in coin with EB>500.
CB Endpoint energy of AP 3300 with T1/2=30-40 S can belong
2CB to the decay of either 202AU or 204AU. 1967Wa23 report
3CB E(B-)=3500 200 with T1/2 AP 30 S and E(B-)=4500 300 with
4CB T1/2 AP 4 S. 1972Pa06 deduce a weak B- feeding to 204HG GS
5CB from the high RI(204HG)/RI(202HG) ratio. 1984Cr01 deduce IB- to GS<10%
6CB from estimate of (N,P) cross sections; other IB- branches are from
7CB G+CE intensity balance, assuming negligible feeding to GS
CB LOGFT Uncertainty does not include the uncertainty in Q-.
