Sensitivity calculations
From Serpent Wiki
Serpent relies on the collision history based first order GPT equivalent implementation (cite to Manu's paper) to calculate sensitivities of various responses to various perturbations. As a simple example, the sensitivity of the effective multiplication factor to the different nuclear cross sections can be calculated.
