CHART Data Input

We welcome your contribution to our numerical databases and submission of your data. Here we describe the format of data files for CHART, which are preferable when we receive and include your data to our databases. But we do accept your data file even when your data does not follow the format.

1. General rule

CHART input data files consist of two types of file: a reference file where bibliographic information is described and a data file where numerical data are given. Following are the general rules to be used in both files.

The length of each line must be less than 128 byte (128 characters). If an item has data with total length longer than 128 byte, use a continuation line with "+". Continuing data must follow "+" without any space after "+".
Each line which is not started with the symbols described above has (1) item name, (2) the item name used in the database (i.e. the column name), and (3) the data, as listed below. Each term is separated with a space or tab.

2.2 Detailes on items

AU

TI

Title of the bibliography.

JN

Journal name. When the data is not published in a journal, write "Private communication".

VI

Volume number of the journal in Arabic numerals.

IP

Page numbers such as 207-250, 207, and L105.

DP

Year of publication.

3.2 Details on items

RN

Record number for which you may put an arbitrary number. It will be renumbered in the database.

PR

Process name. Write "CT" for charge transfer, or "ION" for ionization.

EL

Particle names (chemical symbol). When the incident particle is "A" and the target particle is "B", write "A / B". For example, when the incident particle is nitrogen and the target particle is hydrogen, write "N / H"

ELA

Incident particle name in chemical symbol. (Name of element A.)

ZA

Atomic number of incident particle (element A).

AMA

Atomic mass of incident particle (element A).

INA

Initical ionic state of incident particle (element A). Describe with sign("+" or "-") and Arabic numerals.

IEA

Initial configuration of incident particle (element A), such as 1s² ¹S. Write "1s(2) (2)S", for example.

FNA

Final ionic state of incident particle (element A).

FEA

Final configuration of incident particle (element A). such as 2s2p² ²D. Write "2s2p(2) (2)D", for example.

ELB

Target particle name (chemical symbol). (Name of element B.)

ZB

Atomic number of target (element B).
