Discovery of zinc, selenium, bromine, and neodymium isotopes

  title={Discovery of zinc, selenium, bromine, and neodymium isotopes},
  author={J. L. Gross and Jozef Claes and Jolian Kathawa and M. Thoennessen},
  journal={Atomic Data and Nuclear Data Tables},
Currently, thirty-two zinc, thirty-two selenium, twenty-nine bromine and thirty-one neodymium isotopes have been observed and the discovery of these isotopes is discussed here. For each isotope a brief synopsis of the rst refereed publication, including the production and identication method, is presented.

The production of new neutron deficient isotopes of selenium and arsenic
Abstract The peak of the excitation functions for the production of68,69,70,71Se and68,69,70,71As using heavy ion reactions is given based on the relative amounts of either the isotope of interest orExpand
Band Spectroscopic Observations of the Isotopes of Zinc and Cadmium
ACCORDING to earlier mass-spectroscopic investigations by Aston1, cadmium has the following isotopes arranged in order of their abundances: 114, 112, 110, 111, 113, 116. Later, two additionalExpand
Discovery of the cerium isotopes
The discovery of the 35 cerium isotopes presently known is discussed. Criteria for the discovery of isotopes are suggested and for each isotope a brief summary of the first refereed publication,Expand
The Isotopes of Selenium and some other Elements
THE first experiments with selenium some time ago were not successful. Very satisfactory mass-spectra have now been obtained by vaporising the element itself in the discharge tube. The interpretationExpand
The radioactivity of nickel, copper and zinc
Summary The radioactivity of nickel, copper and zinc induced by neutrons of different energies is investigated. Some new reactions are reported.
New neutron deficient isotopes of krypton
Two new activities were found in the neutron-deficient isotopes of krypton produced by STAp,xn! reactions on bromine. The half lives were determined to be 12.0 plus or minus 1.0 min and 5.5 plus orExpand
New neutron-deficient isotopes of barium and rare-earth elements
Abstract This paper deals with an investigation of the short-lived neutron-deficient isotopes of barium and rare-earth elements. By using the BEMS-2 isotope separator with a heavy-ion beam, weExpand

Constitution of Neodymium, Samarium, Europium, Gadolinium and Terbium
AFTER a long and troublesome series of investigations, I have obtained settings of the apparatus for accelerated anode rays good enough to admit of a provisional analysis of the rare earth elements.Expand
The Constitution of Zinc
THAT zinc was a complex element was demonstrated by Dempster using the method of analysis associated with his name. From the curves published in 1922, he came to the conclusion that the elementExpand
