Collective phenomenon in neon isotopes is an interesting topic.However,even the ground-state deformations cannot be well described by theories.Recently,QJ Zhi and ZZ Ren[Phys Lett B 638:166(2006)]have suggested an improved Nilsson potential,which can give a suitable description of ground-state properties in magnesium isotopes.In order to test the description of neon isotopes located around the‘‘island of inversion’’,we have used this potential to provide the deformed basis for the projectedshell-model calculations.The low-lying spectra and transition properties of neon isotopes can be reproduced reasonably.The gyromagnetic factors of neon isotopes have also been investigated.The structures of excited states along the yrast line are studied in the language of band diagrams.
