The wave properties of the nuclei are demonstrated by the fact that the vibration cannot have an arbitrary strength — i.e. energy — as would be the case with a pendulum for example. Instead, only precise, discrete values known as ‘quantized’ values are possible for the energy. A...

energy at which the beam and target nuclei come close enough in head-on collisions for nuclear forces to significantly influence the reaction mechanism. For such close collisions the population of high-spin states will be enhanced, allowing the rotational behaviour of the nucleus to be elucidated....
Our study is based on a model where the electron remains to two adjacent diatomic molecules vibrating around positions which evolve in time as the charge... D Feinberg,J Ranninger - 《Physica D-nonlinear Phenomena》 被引量: 47发表: 1984年 Approximate constants of motion for classically chaotic...
This paper presents three results, which together, provide new insight into the dynamics of single molecules in nonpolar, nonmetallic liquids: (a) A simple physical model is proposed which suggests that: (i) liquid-state viscosity is produced by temperature-dependent London dispersion forces, and ...
atoms are not conservative.) Equation (40.3), known as Boltzmann's law, is another of the principles of statistical mechanics: that the probability of finding molecules in a given spatial arrangement varies exponentially with the negative of the potential energy of that arrangement, divided by kT...
2020a). In addition, other studies have found that vibrating disc milling can produce more uniformly shaped nanobiochar and has a greater yield than ball milling (Bayram and Öner 2007; Huang et al. 2022). The selection of a suitable milling method for nanobiochar production usually depends ...

The discovery of the electron in 1897 led Lewis to propose the two-electron chemical bond in 1902, although this idea was not published until 191610. Following the introduction of quantum mechanics, Pauling showed that both Kekulé structures, which have the same energy, would resonate to bring...
