Abstract By making use of the method of few-body physics,the energy spectra of low-lying states of a three-electron spherical dot have been calculated. The quantum-size effects on the energy spectra of three electrons are shown.The res ults show that the orders of energy levels do not change when quantum dot diamet ers change. As a result, the energies of the states of L=3k (k=1,2,…) fulfilling $\pi$ (-1)L=1 are lower than those of their adjacent states.

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.
