armi.nuclearDataIO.ripl module¶
Read data from the Reference Input Parameter Library (RIPL-3)
https://www-nds.iaea.org/RIPL-3/
- armi.nuclearDataIO.ripl.getNuclideDecayConstants(fileName)[source]¶
Read the halflifes and makes decay constants for the nuclides in this file.
- Returns
nuclideDecayConstants – decay constants (1/s) indexed to nuclideBases
- Return type
- armi.nuclearDataIO.ripl.readFRDMMassFile(fname)[source]¶
Read file from RIPL containing experimental mass excess evaluations.
This file contains experimental mass excesses as well as theoretical masses from models. This class for the time being only reads the experimental values and skips all others.
The values of interest are defined in the README as:
Z : charge number A : mass number s : element symbol fl : flag corresponding to 0 if no experimental data available 1 for a mass excess recommended by Audi et al. (2007) 2 for a measured mass from Audi et al. (2007) Mexp : experimental or recommended atomic mass excess in MeV of Audi et al. (2007) Err : error on the experimental or recommended atomic mass excess in MeV of Audi et al. (2007) Mth : calculated FRDM atomic mass excess in MeV Emic : calculated FRDM microscopic energy in MeV beta2: calculated quadrupole deformation of the nuclear ground-state beta3: calculated octupole deformation of the nuclear ground-state beta4: calculated hexadecapole deformation of the nuclear ground-state beta6: calculated hexacontatetrapole deformation of the nuclear ground-state
The format is
(2i4,1x,a2,1x,i1,4f10.3,4f8.3).
- armi.nuclearDataIO.ripl.discoverRiplDecayFiles(directory)[source]¶
Discover the RIPL decay/level files in the specified directory.
RIPL decay/level files are like z001.dat where the number represents the atomic number of the nuclides within.
