Clarifying the structure of low-lying states in Br-72

The spins and parities of low-lying states in Br72 populated in the β decay of Kr72 have been studied via conversion electron spectroscopy. The measurements were carried out at ISOLDE using a miniorange spectrometer with Si(Li) and HPGe detectors for electrons and γ ray detection. Results of the con...
