The magnetic-field dependence of the water-proton spin–lattice relaxation time (referred to as nuclear-magnetic-relaxation dispersion) has been measured in colloidal silica suspensions after addition of calibrated MnCl2solutions. The NMRD curves al

Secondary ion yields for dynamic SIMS analysis of oxidized metal and metal oxide surfaces were determined. The dependence of the ion yield with the fragment valence for molecular secondary ion species of the MxOy± type can be described by a Gaussian

Individual rotational levels in the B3 Pi 0+u state of 79Br2 and 81Br2 were excited by an acousto-optically chopped, single-mode Ar+ laser. The intensity of the fluorescent light, measured as a function of time following the laser pulses, was found t

Lifetimes and self‐quenching cross sections of individual rotational levels in the B 3Π0+u state of 79Br2 and 81Br2 were measured by observing the fluorescence decay following excitation by acousto‐optically chopped, single mode Ar+ and Kr+ lase

A technique equivalent to the matrix method of Kramers–Wannier is used to compute the residual entropy per particle on semi‐infinite strips of width n, completely covered by non‐overlapping rectilinear trimers. This thermodynamic quantity is di

A theoretical study of quantum-beat intensity profiles is presented for the case of zero-field hyperfine-structure beats. By means of the graphical methods of angular-momentum theory, an explicit expression for the quantum-beat profiles, in the form

Lifetime measurements of a number of (v, J) rovibronic levels are performed in pure isotopic 81Br2. The gyroscopic and hyperfine predissociation parameters are obtained by mono- and multi-exponential analysis of the fluorescence decay. A comparison o

Polyimides have interesting properties for the preparation of thin substrate foils for nuclear targets, but are not available commercially at the thickness of interest in this field (30–50 μg/cm2). A method was developed to synthetize them in situ
