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.
