Excited levels of 88Br populated in the β decay of 88Se have been studied by means of βγ and γ γ spectroscopy
methods. Neutron-rich parent 88Se nuclei were produced with proton-induced fission of 238U using the Ion Guide
Isotope Separator On-Line (IGISOL) method and separated from contaminants using a dipole magnet and the
coupled JYFLTRAP Penning trap at the Accelerator Laboratory of the University of Jyvaskyl ¨ a. The level scheme ¨
of 88Br has been constructed and log f t values of levels were determined. The ground-state spin of 88Br is
now firmly determined to be 1−. Low-energy levels in 88Br were interpreted as members of the πp3/2(νd5/2)
3,
πp−1
3/2(νd5/2)
3, πf −1
5/2 (νd5/2)
3, and πg9/2νg7/2 multiplets. The shell-model calculations performed in this work
reproduce well the experimental results.
