Abstract

The level scheme of ${}^{102}{Zr}$ has been expanded by measuring high-fold prompt $γ$ -ray coincidence events in the spontaneous fission of ${}^{252}{Cf}$ with the Gammasphere array. Previous identifications have been confirmed. A two-quasi-particle band with a band head energy of 2926.4 keV has been identified for the first time, as well as two rotational collective bands, with band head energies of 1386.3 and 1652.7 keV, respectively. Spins and parties are assigned based on level systematics and angular correlation measurements.
