The preparation of tantalum-free niobium pentoxide

Autor: M. J. Cabell, I. Milner

Publikováno v: Journal of Applied Chemistry. 5:482-483

A method is described whereby the tantalum content of ‘Specpure’ niobium pentoxide can be reduced to a few parts per million without simultaneous contamination of the sample.

Publikováno v: Nonlinear Processes in Geophysics, Vol 24, Iss 1, Pp 77-87 (2017)

In this study, we use multifractal analysis, through generalized dimensions (Dq) and the relative entropy (E(δ)), to investigate the residual effects of fertigation treatments applied to a previous crop on wheat and grain biomass and nitrogen conten

Contract R and D agreements

Autor: M J Cabell

Publikováno v: Physics in Technology. 16:54-57

As money for basic research becomes scarcer many organisations are hoping to capitalise on their existing staff and facilities by carrying out R and D under contract. Success depends upon the customer and the contractor understanding what it is reaso

A CALORIMETRIC DETERMINATION OF THE HALF-LIFE OF THORIUM-230 AND A CONSEQUENT REVISION TO ITS NEUTRON CAPTURE CROSS SECTION

Autor: R. L. Cushing, M. J. Cabell, R. W. Attree, J. J. Pieroni

Publikováno v: Canadian Journal of Physics. 40:194-201

The half-life of Th230 (ionium) has been measured by a calorimetric method and was found to be 75,200 years with a standard error of ± 1,600 years.In the light of this measurement, previously published values for the 2200 m/sec neutron capture cross

Autor: J. P. Butler, T. L. Collins, H. G. Jackson, M. J. Cabell, R. P. Schuman, F. M. Rourke, T. A. Eastwood

Publikováno v: Physical Review. 107:1635-1638

Samples of Bk and Cf have been separated from neutronirradiated Pu and carefully purified. Pure Cf/sup 249/ daughter has been separated from the Bk/sup 249/. The Cf sample and its Cm decay products have been mass analyzed. The Bk fraction contained 3

THE PURIFICATION, DETERMINATION, AND NEUTRON CAPTURE CROSS SECTION OF ACTINIUM-227

Autor: M. J. Cabell

Publikováno v: Canadian Journal of Chemistry. 37:1094-1103

Procedures are described for (a) the separation by ion exchange chromatography of submicrogram quantities of Ac227 from its daughters and (b) the absolute determination of Ac227 by measurement of the rate of growth of α-particle emission from an ini
