// Description: Data structure for cross sections, shell cross sections,
|
|
// isotope cross sections. Data access via integer variable
|
|
// Z (atomic number in majority of applications), which may
|
|
// be in the interval 0 <= Z < length. For isotope like
|
|
// data a second parameter idx or data ID code are used.
|
|
// In most cases ID = A - atomic weight number.
|
|
// There are run time const methods, in which input is not checked
|
|
// assuming responsibility of consumer code. Another run time
|
|
// check input and may throwgh a fatal exception
