Subject:

Quantities and units for thick/thin target yields

Reference:

Memos CP-C/344 and CP-E/040• I appreciate the clean-up efforts of memo CP-C/344. Below I reproduce the tables of thismemo, adding my comments and the appropriate dictionary modifications. This covers
also the changes requested in memo CP-E/040. I agree with the proposals and corrections
submitted in CP-E/040 with one minor exception (dimension code PYT2, see followingpage).

• However, one type of thick target quantities is not listed in CP-C/344 (those with TT inSF8). Tables with those quantities and related remarks are given at the end.

• As suggested in CP-C/344, many quantities which are in dictionary 36 but do not occur inthe database will be made obsolete (they are however not deleted at this stage). Some ofthem are meaningful codes and could become "real" in the future, whenever "real" data ofthese types are compiled for the first time. Therefore, the "obsolete" flag does not always
mean that a quantity is wrong or illegal, and later requests to remove the obsolete flag may
be justified.

Thick target quantities not listed in CP-C/344
These are all quantities with SF8 = TT. These have the same units dimension as thecorresponding quantities with blank SF8. Nevertheless it is important to include them in thelist of thick target quantities (also in LEXFOR) for reference.

The following quantities are used in the database or in a PRELIM file or were proposed
recently in a memo.
