.. list-table:: **IMODE** :phits-same:`PHITS: same name`
   :header-rows: 0

   * - Value
     - Description
   * - (D=0, D\ :sub:`P`\ =2)
     - Calculation type selection.
   * - = 0
     - Induced radioactivity calculation.
   * - = 1
     - Induced radioactivity and decay heat calculation.
   * - = 2
     - Induced radioactivity, decay heat, and :math:`\gamma`-ray spectrum calculation.

.. _`param:jmode`:

.. rst-class:: no-caption-number

.. list-table:: **JMODE** :phits-same:`PHITS: same name`
   :header-rows: 0

   * - Value
     - Description
   * - (D=0, D\ :sub:`P`\ =2)
     - Irradiation condition selection [#]_.
   * - = 0
     - Irradiation with primary beam.
   * - = 1
     - Irradiation with low-energy/secondary neutrons (:math:`<`\ 20 MeV).
   * - = 2
     - Irradiation with primary beam & secondary neutrons (:math:`<`\ 20 MeV).
   * - = -1
     - No irradiation; only decay. ``AMP``\ =0.0 and ``FLUXS``\ =0.0 are enforced.

.. [#]
   Controls whether the yield file (\*.dyld) and/or neutron flux file (\*.dtrk) are used in the calculation.
