Hello everyone I'm simulate alphai2MeVj Backscattering on thin target of gold . I'm interested in energy spectrum at backward angles i160-170 degreejconcerning the Coulombscattering alpha . Because of the thin target I have only a few events in my detector (~100 at an event rate of 10^8). So some kind of cross section biasing seems to be necessary. Most of the alpha are scattered in forward direction (>95% are scattered in an angular range of 0-5 degrees). So in case of alpha scattering "angular biasing" is maybe a good idea that means increasing the cross section for elastic alpha scattering at backward angles relative to the cross section for forward angles by several orders of magnitude. What is the best way to achieve this or someone have other ideas to increase efficent ? Has anyone tried something similar?
Thanks for your helps !
