sw_econtract#

Syntax#

Qm = sw_econtract(Q,Name,Value)

Description#

Qm = sw_econtract(Q,Name,Value) converts \((Q,E)\) values in the phase space into \(Q\) values as it would appear when measuring it with via neutron diffraction.

Input Arguments#

Q

Input values in reciprocal space in the scattering plane in Å\(^{-1}\) units, dimensions are \([2\times n_Q]\).

Name-Value Pair Arguments#

'E'

Energy transfer value in meV, default value is zero.

'lambda'

Wavelength of the incident neutron beam in Å.

'ki'

Momentum of the incidend neutron beam in Å\(^{-1}\), alternative input to lambda.

'sense'

Scattering sense:

  • 1 detectors are on the right hand side from the incident beam direction, default.

  • -1 detectors are on the left hand side from the incident beam direction.
