EvtSpinDensity chigen::models::createSpinDensity	(	int	spin,
		int	projection
	)

Returns momentum density corresponding to particle with total spin

spin 

and spin projection

projection 

.

Parameters

spin	total spin of particle
projection	absolute value of spin projection onto particle momentum and -1 for unpolarized particle
