On the decay of 148 Pm
(Springer-Verlag, 1970-10)
The Β-γ directional correlation between the 1,930 keV Β -group and the 511 keV cascade γ -ray in the 5.4 d 148 Pm decay has been measured at 14 different γ -energy points. The anisotropy is found to be positive and is ...
Analysis of optical propagation in thick holographic gratings
(Springer-Verlag, 1975-05)
A method of analyzing optical propagation in thick holographic gratings by decomposition of the thick material into thin gratings is discussed. The method is readily applicable to study propagation in multiple gratings of ...
Injection and mobility of potassium ions in liquid helium
(Elsevier, 1970-05-04)
Potassium ions from a hot tungsten wire are injected into He II; their mobility is found to be two to three percent lower than that of `normal' positive ions.
The 40Ar([tau], n)42Ca reaction
(Elsevier, 1974-05-13)
The results of an investigation of the 40Ar([tau], n)42Ca reaction at 18.65 MeV incident energy are reported. The weakness of the transition to the 1.84 MeV 0+ level is in disagreement with 4p-2h descriptions of this state.
Magnetism and archaeology: Magnetic oxides in the first American civilization
(Elsevier, 1977)
Archaeological excavations at sites of the Olmec civilization (1500 to 500 B.C. in present-day Mexico) have unearthed artifacts formed from massive iron oxide ores. Iron oxide ores were ground and shaped into highly polished ...
Second class currents and mirror beta decays
(Elsevier, 1971-08-09)
Answers are given to some questions raised by Lipkin concerning the relation between mirror asymmetry in beta-decay and second-class currents. Mirror asymmetry (not of electromagnetic origin) is evidence for second-class ...
Nature of the surface compounds and reactions observed on graphite electrodes
(Elsevier, 1975-09)
The nature and composition of the surface of pyrolytic graphite and the consequent possible effects, when the material is used as an electrode, are considered on the basis of the structure of the graphite and of the handling ...
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 ...
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 ...
Quasinormal distributions and expansion at the mode
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1974-09)
The Gram-Charlier series of type A is discussed in terms of deviants which are related to moments in a way similar to the way Hermite polynomials are related to the powers. Distribution functions are also expressed in terms ...
