Titles: ATPR ============= Contact: N. West, Oxford. Revision History:- ================ 2.08 N. West First version. S. Brice Comment change. 2.09 N. West Comment change. Titles Files ------------ phi_attributes.dat Verification ------------ Description ----------- This titles bank gives the attributes of all process codes. Also see interactions Data Words ---------- Fixed length Database Header. See titles_dbhdr.html I = integer, F = floating point, H = hollerith (4 char) Wd Typ Mnem. Description KATPR_ 1 I Number of words per entry. Then, for each entry:- +1 I CODE Particle or target code. +2 I FLAGS Flags. SOURCE vertex primary particle ID code or 0 if the process cannot be used as a SOURCE vertex. See note 1. +3..H TEXT Description template (50 chars). See note 2. Notes ----- 1. If an interaction code can be used in an MCPI bank the its process code entry will have, as its FLAGS word, the ID of the primary particle produced. For example, for a beta gamma decay, the particle code is that of an electron (E_minus). Some INTERACTION class processes are used in an MCPI. E.g. neutron capture on various isotopes. This enables the user to study the gammas from the capture directly rather than set a neutron off and wait for the capture. 2. Description templates provide a desription of the interaction. The text may contain embedded parameters which can be translated by CHAR_ID_INTERACTIONS. For example:- "Start $CP" The $CP symbol means: take the ccc field and decoded it as a particle name. So, when the routine CHAR_ID_INTERACTIONS is given this interaction code, it will return "Start E_minus". The full set of embedded symbols are:- $TP Decode ttt as a particle $TT Decode ttt as a target $CC Decode ccc as a channel $CP Decode ccc as a particle For $CC:- n=0 is replaced by: "any channel" n>0 is replaced by "channel n"
