controls muon photonuclear interactions
See also PAIRBREM, PHOTONUC
WHAT(1) : flag to switch on muon nuclear interactions: = -1.0 : muon nuclear interactions are not simulated = 0.0 : ignored = 1.0 : full simulation of muon nuclear interactions and production of secondary hadrons = 2.0 : muon nuclear interactions are simulated but no secondary hadron is produced; the energy lost by the muon is deposited at the point of interaction Default = 1.0 if no DEFAULTS card is present, or if it is present with SDUM = CALORIMEtry, NEW-DEFAults, ICARUS or PRECISIOn. = -1.0 otherwise
WHAT(2)-WHAT(3) : reserved for code development
WHAT(4) = lower bound of the indices of the materials, or corresponding name, in which muon nuclear interactions must be simulated ("From material WHAT(4)..."). Default = 3.0.
WHAT(5) = upper bound of the indices of the materials, or corresponding name, in which muon nuclear interactions must be simulated ("...to material WHAT(5)...") Default = WHAT(4)
WHAT(6) = step length in assigning indices. ("...in steps of WHAT(6)"). Default = 1.0
SDUM : not used Default (option MUPHOTON not given): muon nuclear interactions are not simulated
Notes:
Example (number based):
* Explicit pair production and bremsstrahlung requested for heavy charged * particles in materials 12 and 13, provided the energy of the secondary * electrons and positrons is > 500 keV. No threshold is requested for photon * production. For muons, explicit nuclear interactions are also requested. *...+....1....+....2....+....3....+....4....+....5....+....6....+....7....+....8 PAIRBREM 3.0 0.0 0.0005 12.0 13.0 MUPHOTON 1.0 0.0 0.0 12.0 13.0
