NAME
subroutine get_helicityAmplitudes(targetCharge,resonanceID,QSquared,A1,A3,S1,MAID_version_in)
PURPOSE
- Interface for the MAID helicity amplitudes. Returns the helicity amplitudes for a given resonance.
INPUTS
- real, intent(in) :: QSquared ! QSquared in GeV**2
- integer, intent(in) :: targetCharge ! Charge of target nucleon
- integer, intent(in) :: resonanceID ! ID of the resonance according to GiBUU
- integer,optional, intent(in) :: MAID_version_in MAID_version = 1 : use MAID 2003 MAID_version = 2 : use MAID 2005
OUTPUT
- real, intent(out):: A1,A3,S1 ! In units of GeV^(-1/2)
