Abstract

The low-lying level scheme of the odd-odd nucleus ¹³²Pr has been investigated for the first time. The radioactive nuclei were produced by bombarding ⁹⁶Mo targets with a 225 MeV ⁴⁰Ca beam. Levels in ¹³²Pr have been populated from the ¹³²Nd β-decay. A new value of its half-life has been measured: T_{1 2} = 88 ± 7 s. The activities produced in the reaction have been transported with a He-jet device and γγt, Xγt, e^-γt coincidence measurements performed. Internal conversion coefficients have been measured with a magnetic lens spectrometer. The experimental level scheme of ¹³²Pr is compared to theoretical calculations performed with the interacting boson-fermion-fermion model (IBFFM).
