1 ACTAR MEETING Daresbury 12-13/06/06

2 EVENT GENERATOR The angular distribution has been obtained from TWOFNR (DWBA-calculation) 77 Ni(d,p) 78 N i  = 115 Probability of an event occurring in the theta interval from 0 and 180 degrees r=Random number (0,1) If r=0.8->  =122 degrees

3 EVENT GENERATOR I=9/2 Chapel-Hill Beccetti-Greenles *Non-locality: Ingoing=0.54 Outgoing=0.85 *Local Energy Aproximation (LEA)

13 EVENT GENERATOR

14 FULL KINEMATICS from LISE++

15 EVENT GENERATOR The density distribution is described by the equation; Probability of an event occurring in the interval from 0 to z’ Formally, invert the function: z=G(P(z)) Computing: r=Random number (0,1) If r=0.7-> z=0.15
