Analysis of the inelastic scattering of 50 MeV protons
(Elsevier, 1968-09-23)
Differential cross sections and asymmetries for 50 MeV proton scattering from vibrational states in 64,66,68,70Zn and 114Cd have been analysed using a collective-model interaction obtained by deforming the entire optical ...
Heat transfer through gases contained between two vertical cylinders at different temperatures
(Elsevier, 1968-09)
Heat transfer through gases contained between vertical concentric cylinders was investigated when the radius of the inner cylinder is small compared to the radius of the outer cylinder. Experiments were performed in a ...
Neutron-nuclei total cross sections at 27 GeV/c
(Elsevier, 1968-08-05)
The total cross sections for 27 GeV/c neutrons on eight heavy elements, Be through U, has been measured and found to obey the empirical relationship [sigma]T = 48A0.75mb.
On some new production processes for [approximate] 1012 eV muons
(Elsevier, 1968-10-28)
Callan and Glashow and Keuffel have proposed the existence of U and W particles respectively, to explain the lack of zenith angular dependence of cosmic ray muons in the experiment by the Utah group. Arguments are presented ...
Stability of a Horizontal Fluid Interface in a Periodic Vertical Electric Field
(The American Institute of Physics, 1968-07)
The stability of the interface in the presence of a periodic electric field is considered. It is shown that the stability is governed by a Mathieu equation, that the interface can be unstable even if the electric field is ...
Paramagnetic resonance of erbium in CaWO4
(Elsevier, 1968-12-02)
A study has been made of the paramagnetic resonance of Er3+ in single crystal CaWO4. and the parameters of the spin-Hamiltonian determined.
Coulomb displacement energies in the shell
(Elsevier, 1968-06-24)
The experimental Coulomb displacement energies in the shell (except one) can be described by Hecht's Coulomb energy equation with a standard deviation of 8.5 keV if it is assumed that the Coulomb interaction radius is ...
Energy Expectation Values and the Integral Hellmann–Feynman Theorem: H2+ Molecule
(The American Institute of Physics, 1968-08-01)
It is by now well known that the integral Hellmann–Feynman (IHF) theorem has little quantitative utility for chemically interesting problems, although the formalism potentially affords a ready physical interpretation of ...
On the observation of parity admixtures with perturbed angular correlations
(Elsevier, 1968-05-24)
A new parity test is proposed using combined electric and magnetic perturbation of the angular correlation of two gamma rays, one pure and one mixed. The experiment requires a measurement of the asymmetry of the coincidence ...
Total radiances and equivalent widths of isolated lines with combined Doppler and collision broadened profiles
(Elsevier, 1968-08)
Analytical expressions for total radiances and equivalent widths of isolated spectral lines with combined Doppler and collision broadened profiles are presented for isothermal paths.
