The hybrid and GDH model
J.J.Griffin, 1966 : exciton model
G.D.Harp, J.M.Miller, B.J.Berne, 1968 : master-equation approach
M.Blann, 1971 : “hybrid” model
M.Blann, 1972 : “geometry dependent hybrid” model
M.Blann, H.K.Vonach, 1983 :modification and basic improvements
J.Bisplinghoff, 1986 : critical analysis. Configuration mixing
1994 : cluster emission in GDH
M.Blann, 1996 : hybrid Monte Carlo simulation (HMS)
2005 : improvement of cluster emission calculation in GDH
C.A.Soares Pompeia, B.V.Carlson, 2006 : new analysis
2010-2014 : further improvements
