Abstract The decay of Ga has been investigated by means of -ray spectroscopy. The Ga nuclei were produced through the Ga(n, Ga reaction. The Compton-suppressed spectrometer and high-purity Ge detectors have been used singly and in coincidence, separately, to study -rays in the decay of Ga to Ge. Ninety-three events of -rays were reported, of which 7 were observed for the first time. A decay scheme of Ga including 4 new levels is proposed which accommodates 87 of these transitions. Spins and parities for new levels are proposed from calculated log values, modes on the observed decay, and some nuclear reaction experimental results.

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.
