onix.utils.decay_lib

class onix.utils.decay_lib(id_number)

Decay_lib objects allow users to build and store custom, small size decay libraries.

Parameters

id_number (int) – The id number associated with the decay_lib object

add_data(zamid, **kwargs)

Add decay data for a specified nuclide to the decay object.

Note: User can either specify total decay constant (or half life) or specific reactions decay constants (the total decay constant will be deduced from these decay constants).

Parameters

• zamid (int) – z-a-m id of the nuclide

• data (float) –

  Keywords should be decay constants names or the halflife. Input should be the value in \(s^{-1}\) or \(s\). Possible keyword entries:

  • half life

  • total decay

  • betaneg

  • betapos

  • gamma

  • alpha

  • neutron

  • proton

property decay_a

Returns the absolute decay dictionnary of the decay object. This dictionnary has nuclides’ z-a-m id as keys and absolute decay sub-dictionnaries as entries. Absolute decay sub-dictionnaries have decay reactions names as keys and corresponding decay constant absolute values in seconds as entries.

property decay_b

Returns the fractionnal decay dictionnary of the decay object. This dictionnary has nuclides’ z-a-m id as keys and fractionnal decay sub-dictionnaries as entries. Fractionnal decay sub-dictionnaries have decay reactions names as keys and corresponding decay constant as fraction of total decay constant for entries.
