Discovery of dysprosium, holmium, erbium, thulium, and ytterbium isotopes

Abstract

Currently, 31 dysprosium, 32 holmium, 32 erbium, 33 thulium and 31 ytterbium isotopes have been observed and the discovery of these isotopes is discussed here. For each isotope a brief synopsis of the first refereed publication, including the production and identification method, is presented.

2014 update of the discoveries of nuclides

“…This is the second update of the isotope discovery project which was originally published in a series of papers in Atomic Data and Nuclear Data Tables beginning in 2009 with the discovery of the cerium isotopes 1 and was completed with the publication of the discovery of dysprosium, holmium, erbium, thulium, and ytterbium isotopes in 2013. 2 Subsequently, comprehensive overviews were published in 2012 and 2013 in Nuclear Physics News 3 and Reports on Progress in Physics, 4 respectively. The present journal published the first update at the beginning of last year.…”
