In this paper we consider the extent of our knowledge of global beetle diversity. Depending on the estimates adopted, some 70–95% of all beetle species remain to be formally described, and at the current rate of progress it could be more than 200 years until the task is completed. One of the reasons for this is the difficulty of adequately sampling tropical beetle faunas and thereby ensuring su...

A survey is given of experimental studies of electron attachment and recombination in dense molecular media, from which information on the effect of van der Waals potentials or on the existence of surrounding molecules on these processes is obtained.

An optical study has been made of La0 ·7Ca0 ·3MnO3 and La0 ·8Li0 ·2MnO3 in the infrared spectral region (100 cm−1 to 4000 cm−1). The transmission of all samples is negligible. The photoconductive response is also unmeasurable. The data reported are therefore restricted to reflectivity measurements. At room temperature, both materials exhibit similar ‘bending’ and ‘stretching’ phonon modes, asso...

Accurate low-energy electron scattering data are needed in many fields of physics. However, accurate experiments are difficult to design and to carry out. By 1967 low-energy electron–He cross sections had been measured by two different techniques, designed to provide accurate data. Unfortunately, the data differed by amounts well outside the estimated error bars. Despite the relative simplicity...

A critical look is made of discrepancies and agreements between new and old measurements and theories for elastic and n = 2 excitation of atomic hydrogen by electron impact, mainly at 16 ·5, 54 and 100 eV. A discussion of earlier work indicates the contributions of Weigold and colleagues. The difficulties of observing and modelling small scattered fluxes at backward scattering angles and of mak...
