Abstract Isotope shifts and hyperfine spectrum of singly ionized neodymium ion was measured by collinear fast-ion-beam laser spectroscopy. The hyperfine A constants and B constants are obtained for the (23230)o9/2 level and 4f45d 6K9/2 level, respectively. The optical isotope shifts between seven isotopes in the 580.56 nm of 142-145,146,148,150Nd+ line are determined. The configuration admixtures for (23230)o9/2 level were quantitatively analysed to be 4f46p, 4f35d2, and 4f35d6p with mixing coefficients of 67%, 5%, and 28%, respectively.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
