[Gate-users] Changing cross section of Compton effect

Hello,

In my simulation, I simulate plastic scintillators. Beam of gamma particles
with energy 511 keV is directed into plastic scintillator.
I would like to have a situation, where all of gamma particles that attach
the scintillator, cause the scintillation process and production of optical
photons.
In order to do it, I would like to modify cross section of Compton effect.

In help of GATE I found something like that:

Command /gate/physics/processes/Compton/activateCSEnhancement
Guidance :
Activate cross-section enhancement

Parameter : Particle
 Parameter type  : s
 Omittable       : False

Parameter : factor
 Parameter type  : d
 Omittable       : False

This command is not described in wiki of GATE. How should it be used?

For example, if I would like to increase the Compton effect by a factor 10,
should I write:

/gate/physics/processes/Compton/activateCSEnhancement Gamma 10

?
