(19800116U) ND. APRVD entered 3047200100030
(19811022A) VP. Two subentries were canceled. Final 3047200100031
values were entered in EXFOR 30605005 and 30605006. 3047200100032
The reason is that final publication in Ann.of Nucl. 3047200100033

COMMENT By author: 3047200500005
The large error in the cross-section is due to the 3047200500006
presence of 204Pb(n,n')204mPb whose contribution was 3047200500007
estimated and subtracted in the present measurement. 3047200500008
CRITIQUE By compiler: 3047200500009
The quoted value of 1.2 mb is not possible, as the 3047200500010
energy, 14.2 MeV, is 1.6 MeV below the threshold for 3047200500011
above reaction. The authors do admit to have subtracted3047200500012
a large background from the interfering reaction 3047200500013
204Pb(n,inl)204mPb, which may explain this discrepancy.3047200500014
