atompy.physics.compton_scattering.calculate_Q_neglecting_mom_init(incoming_photon_momentum, final_elec_momentum)[source]#

Calculate momentum transfer with the approximation that the energy of the outgoing photon equals the energy of the incoming photon.

Parameters:
incoming_photon_momentumVector

momentum of incoming photon in a.u., incoming photon is assumed to be along x-axis

final_elec_momentumVector

final electron momenta in a.u.

momentum_transferVector

momentum transfer

Returns:
vectorsVector

shape (N, 3), the momentum transfers
