In this work nuclear structure properties of 86,87,88,89 Y isotopes have been investigated using large-scale shell-model calculations within the full f 5/2 pg 9/2 model space. The calculations have been performed with JUN45 and jj44b effective interactions that have been proposed for use in the f 5/2 , p 3/2 , p 1/2 , g 9/2 model space for both protons and neutrons. Reasonable agreement between experimental and calculated values are obtained. This work will add more information to previous study by projected shell model [Eur. Phys. J. A 48, 138 (2012)] where full-fledged shell model calculations proposed for these nuclei.
