35 | // Process for nuclear capture of mu- at rest takes into account Fermi |
---|
36 | // model of muon capture in compounds, simplified EM cascade model, muon |
---|
37 | // decay from K-shell, and muon nucleus reaction. |

40 | // Modifications: |
---|
41 | // 18/08/2000 V.Ivanchenko Update description, new method to simulate capture |
---|
42 | // 12/12/2003 H.P.Wellisch Completly rewrite mu-nuclear part |
---|
43 | // 17/05/2006 V.Ivanchenko Cleanup |
---|
