of transmission increases and decreases sinusoidally with decreasing amplitude when energy is increased. In this case, on increasing the energy of the particle E, transmittivity decreases or increases sinusoidally which is against classical notions.
Transmittis
.. . Evo *** Here in diagram is shown transmittivity as a function of incident energy. Classically the transmittivity must go on increasing with increasing energy but actually it is found to decrease also, for some ranges of energies. In fact there the particle struggles for its behaviour as a wave or as a matter. Also peculiar is the case of identical colliding particles where there can be no distinction between the target and the incident particles. Here the scattering cross-section will be very much different than the classical estimates. In fact it will be sum of two individual cross-sections (first with particle l as incident, particle 2 as target and second with particle 2 as incident and particle 1 as target) and an additional term due to the interference of the two matter waves. Also in resonance scattering of a particle by patential well v phenomenon which has no classical analogue. Here, when the energy of particle is decreased, it may cross the well, while on increasing energy it may cease crossing the well.
The radius of an atom is the distance at which the probability of finding the electron is maximum. In fact this is the definition under the assumption of point charge of proton. If the charge of nucleus is assumed to be distributed over a surface of radius R. (Nuclear radius) the Bohr's model of atom (say-H-atom) needs some corrections to ordinary Bohr spectrum. It is interesting to note that under some modifications of the model, the electron is found to penetrate into the nuclear core which one can not believe on classical grounds, as two solids as such can not penetrate into each other. In fact this event is an interference of two waves. Also in case of zero energy there can exist a bound state under Quantum mechanical concepts while it is untenable according to the classical picture. In decay the case of zero energy yields results not confirming to causation laws.
