Many people still think of atomic energy as a matter of scientists with scientific assistants and laboratories with laboratory-type equipment. The factories of the Industrial Group of the U.K. Atomic Energy Authority are controlled and directed by engineers and industrial chemists as well as by physicists, most of whom must be as skilled in management as they are in the technical complexities o...

The distinct nature of the cold fusion regime is emphasized: electromagnetic selection rules suppress radiation, permitting excess energy transference to the lattice; the coherent nature of the wave-function is at variance with the standard separation between barrier penetration and nuclear reactivity. The discussion is restricted to tritium production, based on the dd reaction that populates t...

The instantaneous displacement, velocity and acceleration of a cantilever tip impacting onto a graphite surface are reconstructed. The total dissipated energy and the dissipated energy per cycle of each excited flexural mode during the tip interaction is retrieved. The tip dynamics evolution is studied by wavelet analysis techniques that have general relevance for multi-mode atomic force micros...

Most of the variational Monte Carlo applications on quantum chemistry problems rely on variance-optimized wave functions. Recently, M. Snajdr and S. M. Rothstein, @J. Chem. Phys. 112, 4935 ~2000!# have concluded that energy optimization allows one to obtain wave functions that provide better values for a wide variety of ground state properties. In this work we study the quality of energy-optimi...

We extend Van der Corput's method for exponential sums to study an oscillating term appearing in the quantum theory of large atoms. We obtain an interpretation in terms of classical dynamics and we produce sharp asymptotic upper and lower bounds for the oscillations.
