The Mass-spectrum of Indium [PDF]
Nature, 1924 SINCE the last report on the results of the massspectrograph (NATURE, September 22) the work with that instrument has been very disappointing. Owing partly to the capricious behaviour of the apparatus for producing accelerated anode rays, with consequent difficulties in obtaining intense beams, and partly, no doubt, to the unfavourable properties of ...

On the Thermomechanics of Hadrons and Their Mass Spectrum
ParticlesA little-known thermomechanical relation between entropy and action, originally discovered by Boltzmann in the classical domain, was later reconsidered by de Broglie in relation to the wave–particle duality in the free propagation of single particles. In
