Reaction Names – pyne.rxname

Python wrapper for rxname library.

The rxname module provides a string-based canonical form for reaction channel names, an integer identifier, labeling and documentation, and conversion to/from other conventions for these names.

Reaction Names: The names themselves are strings chosen such that they are valid variable names in most programming languages (including Python and C/C++). This strategy is known as natural naming and enables a namespace of reactions. Therefore, all names must match the regular expression [A-Za-z_][A-Za-z0-9_]*. For example, the elastic scattering cross section is simply “elastic” while the pair production reaction is given by “pair_prod”.

A number of patterns dictate how a reaction should be named. Foremost among these are particle names. Where required, “z” is a variable for any incident particle. The following table displays particle types and their names:

particle name (z)
neutron n
proton p
deuterium d
tritium t
Helium-3 He3
alpha a
gamma gamma

From this we can see that a reaction which produces a neutron and a proton is called “np”. If multiple particles of the same type are produced, then the number precedes the particle type. Thus, one neutron and two protons are given by “n2p”. However if this would result in the name starting with a number, then the name is prepended with z_ to indicate any incident particle. For example, the reaction which yields two neutrons is “z_2n” (because “2n” is not a valid variable name in most programming languages).

Furthermore, if a reaction name ends in _[0-9]+ (underscore plus digits), then this means that the nucleus is left in the nth excited state after the interaction. For example, “n_0” produces a neutron and leaves the nucleus in the ground state, “n_1” produces a neutron and the nucleus is in the first excited state, and so on. However, “_continuum” means that the nucleus in an energy state in the continuum.

If a reaction name begins with erel_, then this channel is for the energy release from the reaction by the name without erel_. E.g. “erel_p” is the energy release from proton emission.

Reaction IDs: While the reaction names are sufficient for defining all possible reactions in a partially physically meaningful way, they do so using a variable length format (strings). It is often advantageous to have a fixed-width format, namely for storage. To this end, unique unsigned 32-bit integers are given to each name. These identifiers are computed based on a custom hash of the reaction name. This hash function reserves space for MT numbers by not producing values below 1000. It is recommended that the reaction identifiers be used for most performance critical tasks, rather than the names that they are calculated from.

Reaction Labels: Reaction labels are short, human-readable strings. These do not follow the naming convention restrictions that the names themselves are subject to. Additionally, labels need not be unique. The labels are provided as a convenience for building user interfaces with.

Reaction Docstrings: Similar to labels, reactions also come with a documentation string which gives a description of the reaction in a sentence or two. These provide more help and information for a reaction. This may be useful in a tool tip context for user interfaces.

Other Canonical Forms: This module provides mappings between other reaction canonical forms and the naming conventions and IDs used here. The most widespread of these are arguably the MT numbers. MT numbers are a strict subset of the reactions used here. Further information may be found at [NNDC], [NEA], [T2], and [JAEA].

The rxname module implements a suite of functions for computing or retrieving reaction names and their associated data described above. These functions have a variety of interfaces. Lookup may occur either by name, ID, MT number, a string of ID, or a string of MT number.

However, lookup may also occur via alternate names or abbreviations. For example, “tot” and “abs” will give the names “total” and “absorption”. Spelling out particles will also work; “alpha” and “duet” will give “a” and “d”. For a listing of all alternative names see the altnames variable.

Furthermore, certain reactions may be inferred from the nuclide prior and post reaction. For example, if an incident neutron hit U-235 and Th-232 was produced then an alpha production reaction is assumed to have occurred. Thus most of the functions in rxname will take a from nuclide, a to nuclide, and z – the incident particle type (which defaults to “n” neutron). Note that z may also be “decay”, indicating a radioactive decay occurrence.

Adding New Reaction Names

If for some reason the existing reaction names are insufficient, the following procedure will add a new reaction to the suite provided.

  1. Increment NUM_RX_NAMES in “rxname.h”.
  2. Add the name to the _names array at the top of “rxname.cpp”. Note the location in this array that the new name was added.
  3. In the _fill_maps() function in “rxname.cpp”, add the MT number to the _mts array at the same index the name was added in step 2. If the reaction does not have a corresponding MT number, add a zero (0) at this location instead.
  4. In the _fill_maps() function in “rxname.cpp”, add a short label to the _labels array at the same index the name was added in step 2.
  5. In the _fill_maps() function in “rxname.cpp”, add a docstring to the _docs array at the same index the name was added in step 2.

Repeat this procedure as necessary.
