Abstract We study the ground state properties of light hypernuclei theoretically using the relativistic mean-field theory with TM1 and NL-SH force parameters. It is found that these new parameters can satisfactorily reproduce the ground state properties of the light hypernuclei even near the neutron drip-line. The parameter sets TM1 and NL-SH give a very similar description of hypernuclei. The properties of hypernuclei in baryon-hyperon systems are insensitive to the force parameters of effective nucleon nucleon interactions. We also take into account the influence of pairing forces on the Λ hyperon and find that it leads to an even-odd effect in light hypernuclei.

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.
