EVENT GENERATOR
The angular distribution has been obtained from TWOFNR (DWBA-calculation)
77Ni(d,p)78Ni
= 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
EVENT GENERATOR
I=9/2
Chapel-HillBeccetti-Greenles
*Non-locality:
Ingoing=0.54
Outgoing=0.85
*Local Energy Aproximation (LEA)
KINEMATICS
theta_ proton
energy_ proton
theta_ 78Ni
energy_ 78Ni
phi angles chosen randomly from an isotropic distributions between 0-360GEANT4 creates 2 vertex :
momemtum_x=sin(theta)*cos(phi)
momentum_y=sin(theta)*sin(phi)
momentum_z=cos(theta)
