Webb, the probability density corresponding to finding a particular eigenstate f is given by: U (f) f i2 (3) This expression is obviously always positive. It is well known that a problem arises in the relativistic case when an attempt is made to include position x in this framework. Webb13 feb. 2009 · They said zero probability density means you have zero chance of seeing the particle. It doesn't mean the particle never arrive there. Only because of wave function interference, we have zero chance to see them. For example, oscillator excited state, there are several nodes in the wave function.

The reason why a physical quantity such as probability is given by Ψ 2 rather than some other function of Ψ is geometry, namely Pythagoras' theorem. If you have a vector which points from the origin to the ( x ^, y ^, z ^) coordinates ( x, y, z), then the length ℓ is given by ℓ 2 = x 2 + y 2 + z 2. doughegoji 2021Webb10 apr. 2024 · Characterization and assessment of projection probability density function and enhanced sampling in self-collimation SPECT April 2024 IEEE Transactions on Medical Imaging PP(99):1-1 dough gods
