I posted not so very long ago about the announcement of the discovery of a hitherto unobserved isotope of lead. The same laboratory has now had the announcement published about the observation of two further new isotopes; 240Es (Einsteinium, element number 99) and 236Bk (Berkelium, element number 97)
Congratulations to the team, drawn from the home institution of the laboratory, Jyväskylä University, as well as from collaborating institutions around the world.
If you want to read the research paper, it is published as an open access paper (i.e. anyone can read it without a subscription to the journal) here. The publication date of the journal issue in which the paper features is in 2017, strangely.
