Specific heat of para-hydrogen monolayers on graphite
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1974-12)
The specific heat of para-hydrogen films has been measured from 1 to 20 K for areal densities between 0.01 and 0.055 atoms/Å 2 of the partial monolayer adsorbed on grafoil. The results are compared with the specific heat ...
Transient heat transfer in a thick thermal boundary layer with spherical symmetry
(Elsevier, 1977)
Unsteady heat diffusion in a thick thermal boundary layer over a spherical surface in radial motion is studied. The boundary layer is divided into two parts, one towards the outer edge of the layer, and the other adjacent ...
A class of loss functions of catenary form
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1973-03)
The catenary form of loss function is considered in the framework of Bayesian decision theory. The mathematical tractability of this form seems to be unrecognized; it contains quadratic loss as a limiting case. For various ...
Redundancy modulation for coherent imaging systems
(Elsevier, 1973-01)
In order to image continuous-tone transparencies with coherent light, special types of diffuse speckle-free illumination are required to achieve high image quality. Several types of speckle-free modulation have been ...
The weak coupling model applied to the nuclei with A = 16-19: (I). Energy levels
(Elsevier, 1970-03-31)
We have formulated particle-hole states by coupling in J and T eigenfunctions resulting from diagonalization of (sd)n1 and pn2. A central particle-hole interaction is assumed and the results for the negative parity levels ...
On the bound states of the massless free field in two space-time dimensions
(Elsevier, 1976-12-06)
We point out the peculiar kinematics of zero-mass fields in two space-time dimensions by showing that the n-fold tensor product of one-particle representations of the Poincare group for n [ges] 2 contains a countable ...
Measurements of hyperpolarizabilities for some halogenated methanes
(The American Institute of Physics, 1974-01-15)
dc Electric‐field induced optical second‐harmonic generation has been measured for CH4, CH3F, CH2F2, CHF3, CF4, CClF3, and CBrF3. For CH4 and CF4 the third order hyperpolarizability χ(−2ω; 0,ω,ω) is obtained directly. For ...
High Temperature Electronic Structure of Fe3O4Fe3O4
(The American Institute of Physics, 1976-09-01)
The high temperature electronic structure and conduction mechanism in Fe3O4Fe3O4 have been investigated through correlations of resistivity and magnetoresistance data with 57Fe NGR. Similar to the resistivity, the relative ...
A description of drift chambers used in a Fermilab experiment
(Elsevier, 1976-11-01)
We give a detailed description of the drift chamber system used in a charm search at Fermilab. All important aspects of design and performance are discussed.
Properties of the (: ϕ4 :)1 + 1 interaction Hamiltonian
(The American Institute of Physics, 1974-06)
Using a convergent expansion of the resolvent of the Hamiltonian H = H0+λV,V = ∫ dx×(x):φ4:(x),g(x) ∊ C0∞,g(x) ≥ 0H=H0+λV,V=∫dx×(x):φ4:(x),g(x)∊C0∞,g(x)⩾0, we give a simple proof of (a) the self‐adjointness of the Hamiltonian ...
