Gamma-gamma directional correlations in 140Ce
(Elsevier, 1971-11-29)
Directional correlation measurements have been performed on six [gamma]-ray pairs occurring in the de-excitation of 140Ce. Of these, two are 1-3 correlations with an unobserved intermediate [gamma]-ray. Both NaI(T1)-Ge(Li) ...
Determination of mixing ratios from the gamma-gamma directional correlations in a triple cascade
(Elsevier, 1973-06-15)
Formulas for the determination of the three mixing ratios in a triple cascade have been derived and expressed in terms of the directional correlation coefficients of [gamma]1-[gamma]2, [gamma]2-[gamma]3 and [gamma]1-[gamma]3 ...
Recent Results from the NAL Bubble Chamber
(The American Institute of Physics, 1973-06-01)
We present a summary of results obtained during the last few months from the 30‐inch hydrogen bubble chamber at National Accelerator Laboratory.
Neutron-deuteron elastic scattering from 6 to 12.5 GeV/c
(Elsevier, 1976-03-01)
The differential cross section for neutron-deuteron elastic scattering was measured for four-momentum transfers 0.3 t 2 with incident neutron momenta between 6 and 12.5 GeV/c. The measurement was made with spark chambers ...
Energies and mixing ratios of transitions in 72Ge
(Elsevier, 1974-02-04)
The lower energy [gamma]-rays of 72Ge from the decay of 14 h 72Ga have been studied using a 2 m curved-crystal spectrometer. Mixing ratios for the 601, 630, 894 and 1051 keV transitions were determined from the [gamma]-[gamma] ...
MnWO4, calorimetric study of the bifurcated antiferromagnetic anomaly
(The American Institute of Physics, 1976-05)
The heat capacity of a powdered MnWO4 sample has been measured from 5–350 K. The data show three anomalies below 20 K: a small peak at 6.8±0.1 K, then two large sharp peaks at 12.57±0.05 and 13.36±0.05 K. The magnetic ...
Rho-omega interference in pp 4st AT 1.6 - 2.2 GeV/c *
(Elsevier, 1970-12-15)
The [pi]+[pi]- mass spectrum from over 3000 events of the reaction pp-->[pi]+[pi]+[pi]-[pi]- at 1.63-2.20 GeV/c shows evidence for [rho]-[omega] interference. If we allow for [rho]-background interference the evidence is ...
On the maintenance of the axisymmetric part of the flow in the atmosphere
(Birkhäuser-Verlag; Springer Science+Business Media, 1972-12)
The maintenance of the axisymmetric component of the flow in the atmosphere is investigated by means of a steady-state, quasi-geostrophic formulation of the meteorological equations. It is shown that the meridional variations ...
Fe3O4 Verwey transition. Calorimetric determination of the effects of concentration of Zn and Cd dopants
(The American Institute of Physics, 1975-04)
To determine the effect of increase of the lattice constant and decrease in electron concentration on the Verwey transition in Fe3O4, heat capacity measurements have been made on Zn− and Cd−doped Fe3O4 from 5 to 350 K. ...
Structure of the 12j and 15j coefficients in the Bargmann approach
(The American Institute of Physics, 1974-09)
Generating functions of the 12j and 15j angular momentum recoupling coefficients are computed explicitly in the Bargmann formalism. Symmetry properties are deduced therefrom. A geometrical Möbius strip representation ...
