Relationship between electron density and effective densities of body tissues for stopping, scattering and nuclear interaction of proton and ion beams
electron density body tissues proton and ion beams
2011/9/9
In treatment planning of charged-particle radiotherapy, patient heterogeneity is normally modeled as variable-density water to best reproduce the stopping power. This water-based model would cause sub...
Time-delay of classical and quantum scattering processes: a conceptual overview and a general definition
Time-delay classical quantum scattering processes conceptual overview general definition
2010/11/8
We present a step by step introduction to the notion of time-delay in classical and quantum mechanics, with the aim of clarifying its foundation at a conceptual level. In doing so, we motivate the in...
