Interaction of massless fermions with instantons
(Elsevier, 1979)
We develop a systematic method of calculating the massless fermion propagation function and fermion-induced effective action in the background gauge field of an arbitrary number of widely separated instantons and ...
Interface separation in the transonic range caused by a plane stress pulse
(Elsevier, 1979-02-08)
This is a continuation of the authors' investigation [1] of the localized separation between two contacting solids that is caused by an incident plane elastic wave of arbitrary form. The interface is taken as frictionless ...
First observation of the ( 4 He, 8 B) reaction
(Springer-Verlag, 1979-09)
The ( 4 He, 8 B) reaction on 27 Al and 66 Zn targets has been studied at E α =109MeV, the first observation of this reaction. Five groups appear in the first 4 MeV of excitation in the 23 Ne spectrum, with laboratory ...
High temperature–high pressure thermal conductivity of argon
(The American Institute of Physics, 1979-04-15)
A conductivity column‐type apparatus was built and tested for measuring the thermal conductivities of gases at high temperatures and at high pressures. Two columns of different lengths were used in order to minimize end ...
A positron annihilation study of carbon black and carbon-black-filled polybutadiene
(Springer-Verlag, 1979-01)
Studies have been made on positron lifetimes in carbon blacks and carbon black filled polybutadiene. The results for the carbon blacks can be interpreted with the aid of the theoretical results of Brandt and Paulin: Phys. ...
High temperature–high pressure thermal conductivities of ethylene and propane
(The American Institute of Physics, 1979-04-15)
Thermal conductivities λ of ethylene and propane were measured in the temperature and pressure ranges 400–750 K and 0.1–2.65 MPa (ethylene) and 400–725 K and 0.1 to 0.6 MPa (propane). The data were correlated by expressions ...
Spectroscopic and optically detected magnetic resonance studies of PO2- in potassium chloride. II. Magnetic resonance analysis
(Elsevier, 1979-07-15)
The optically detected magnetic resonance (ODMR) spectrum of phosphorus activated potassium chloride crystals obtained at 2 K in zero and weak applied external magnetic fields is reported and analyzed. A theoretical fit ...
Ground state energy of small electron-hole drops
(Elsevier, 1979-01)
The ground state energy of small electron-hole drops is calculated for droplets ranging in size from 10 to 10,000 pairs. A new value for the bending energy of 1.1 x 10-10 erg/cm is derived. We also give a simple highly ...
On the simultaneous elongation and inflation of a tubular membrane of BKZ fluid
(Elsevier, 1979)
This work considers a viscoelastic fluid membrane which is initially tubular and bonded at each end to a rigid circular disc. The membrane is subjected to prescribed elongational and internal pressure histories causing it ...
On the contribution of direct intermacromolecular interactions to the viscosity of a suspension of hard spheres
(The American Institute of Physics, 1979-08-01)
The contribution of the contact interaction to the shear and bulk viscosities η and ηv of a suspension of hard spheres : is evaluated by use of the Green–Kubo integral forms. To lowest (second) order in the volume fraction ...
