Replacement for pages 5 9 - 2 - 1 1 0 through 5 9 - 2 - 1 1 7 and 6 - 2 , 3 - 3 0 2 and 6 - 2 , 3 - 3 0 3 of Nuclear Data Sheets
Level schemes, compilers' analysis sheets, and data s h e e t s follow immediately. References, explanations of conventions, symbols, and abbreviations are at the back of this issue. P o l i c i e s and b a s e s for spin-parity assignments are described in the front of the first issue of each volume. Explanation of report identifications (BNL, ISC, etc.) and a list of USAEC Depository Libraries in countries outside the USA through which reports may be obtained are given with the reference section of the first i s s u e of each volume. References to reports are not used if a journal reference is available. P l e a s e refer to a specific Nuclear Data Sheet by using the number at the bottom of the page in the following way: Nuclear Data B1-2-69 (1966).

Level schemes, compilers' analysis sheets, and data s h e e t s follow immediately. References, explanations of conventions, symbols, and abbreviations are at the back of this issue. P o l i c i e s and b a s e s for spin-parity assignments are described in the front of the first issue of each volume. Explanation of report identifications (BNL, ISC, etc.) and a list of USAEC Depository Libraries in countries outside the USA through which reports may be obtained are given with the reference section of the first i s s u e of each volume. References to reports are not used if a journal reference is available. P l e a s e refer to a specific Nuclear Data Sheet by using the number at the bottom of the page in the following way: Nuclear Data B1-2-69 (1966).
