Derivation of classical and quantum statistical distributions
Autor: N. C. Barford
Publikováno v: American Journal of Physics. 44:940-943
An elementary method is described for deriving the Boltzmann, Fermi–Dirac, and Bose–Einstein distributions that neither uses Lagrange undetermined multipliers nor requires a knowledge of Stirling’s approximation for ln(n!). Apart from giving a

Reversible energy converter
Autor: N. C. Barford
Publikováno v: American Journal of Physics. 49:460-465
A device for illustrating the reversible conversion of thermal energy to mechanical work is discussed theoretically and quantitative design parameters are given for constructing a laboratory scale model. Preliminary results show that avoidance of fri

The Radiative Capture of Protons by Neutrons at 50 MeV
Autor: N C Barford, B Tallini, R B Palmer
Publikováno v: Proceedings of the Physical Society. 78:912-917
By using an internal lithium deuteride target in the Harwell cyclotron, and `hardening' the resulting scattered neutrons with polythene, a low intensity beam of neutrons with an energy peak at 50 MeV was produced. This beam passed through a 9 cm hydr

The angular distribution and attenuation of the star-producing component of cosmic rays
Autor: N. C. Barford, G. Davis
Publikováno v: Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences. 214:225-237
Some properties of cosmic rays at 3570 m have been studied by observing nuclear dis-integrations in G5 emulsion under lead absorbers. Good geometrical definition was ensured by making these absorbers in the form of inverted lead cones of various half

The most probable path of a scattered particle
Autor: N. C. Barford
Publikováno v: Il Nuovo Cimento. 18:1274-1276
A graphical method for determining the most probable path of a particle through a plate of scattering material has been described by Barfond and Reynolds (Nuovo cimento, 4: 929(1956)). A generalization of the theory involved is offered which allows a
