The authors reply to the comments presented by J.S. Wykes (see ibid., vol.15, no.12, p.1386) in which the author has disputed the advantage of using pseudorandom beam widths. The authors find the comments helpful in elucidating the complex interactio

The polarization state of the photoelectrons emitted by an assembly of ground state alkali atoms illuminated by circularly polarized light is described in terms of the Stokes vector formalism. The results indicate that there are several different exp

SynopsisThe general paraxial particle-optic properties of the hexapole field are summarized and lens formulae derived. Formulae are given for the transmission as a function of particle velocity and system geometry for geometries appropriate to the ca

A method is suggested for measuring the polarization of low-energy electron beams by observing the polarization of the light emitted by mercury atoms following their excitation by electron impact. It is shown that the asymmetry of the left and right

This paper describes a novel fibre optic methane sensor which has several advantages over previously published fibre optic techniques. It is based on a scanning Fabry Perot etalon filter and is self-referencing, requiring only a single optical sensin

The author criticises a claim by Mehrdadi et al., (see ibid., vol.15, p.367-72, 1982) that the use of pseudorandom beam widths provides a better method of pulse/echo ranging on rough targets than conventional fixed beam shape pulse/echo systems since
