29 // Bertini Cascade dineutron class implementation file
30 //
31 // History: first implementation, inspired by G4Proton
32 // 17 Nov 2009: Michael Kelsey
33 // 06 Apr 2010: Do G4Ions initialization in ctor.
34 // 13 Apr 2010: Per Kurashige, inherit from G4VShortLivedParticle.
35 // 06 May 2010: Remove created particle from master table.
36 // 25 May 2012: Add flags to suppress particle-table error message.
37 // 01 May 2013: Remove G4ThreadLocal from static pointer.
