Subject: 1. Coded information for INC-SPECT
2. C0430 in TRANS C018

1. INC-SPECT
EXFOR Manual (see p.8.1.1) contains the rule:"Used to provide information on the characteristic and resolution of theincident-projectile beam. See also LEXFOR Incident-Projectile Energy.
Presence is optional, except that it is required when the quantity modifiers MXW, SPA
or FIS are present under REACTION (see page 6.8) See also LEXFOR Incident-Projectile
Energy and Spectrum Average. No coded information"
EXFOR Basics (see p.B.4) contains another rule:"Provides free text information on the characteristics and resolution of theincident-projectile beam"
LEXFOR (see R.10)
requests to use INC-SPECT to describe Incident-particle Energy Resolution and does
not request to describe Angular Resolution.
-----------------------------1.1 We know, that angular resolution and energy resolution are identical important foran experiment, because the energy of reaction products is the function of an angle.
Therefore I would like to propose use INC-SPECT to describe angular resolution too.
This proposal does not contradict the rule for INC-SPECT, which is included inEXFOR Basic.
1.2 LEXFOR requests "The shape and definition of the resolution function should begiven in free text under INC-SPECT". This rule can not be assumed as suitable, because
computer checking for this rule is impossible.
Today we have unique possibility to check:
IF(('EN-RSL' is present).AND.('INC-SPECT' is absent) ) THEN 'ERROR'.
We can not check what characteristic is described in INC-SPECT!
Coded information is needed for computer checking.
The absence of similar computer checking permits for a compiler "to forget" to give anexplanation for energy and angular resolutions.
Dr. O. Schwerer took our attention to our mistakes regarding to EN-RSL (see, forexample, MEMO CP-D/261). But his remarks are equitable for another Center's compilations.
(see, for example, C0017, C0040, C0045, C0050, C0054, C0424, C0047, C0062, C0104,C0108, C0380)
Another example: C0035 used EN-RSL, but INC-SOURCE describes EN-RSL-HW.
1.3 We would like to propose to change the rule for INC-SPECT in EXFOR Basic:"INC-SPECT Provides the information on the characteristics and resolution of theincident-projectile beam.
Coded information + free text or free text only can be used. Codes must include
substring '-RSL'. These codes are found in Dictionary 24. Needed elucidation must be given
in free text."
1.4 Our proposal could be discussed at nearest Technical Meeting.
