The odd-Z isotope ²⁵⁵Lr, its daughter ²⁵¹1Md and grand-daughter ²⁴⁷Es were studied in two experiments performed at GANIL and the University of Jyväskylä. The ²⁵⁵Lr nuclei were produced using the cold fusion-evaporation reaction ²⁰⁹Bi(⁴⁸Ca, 2n)²⁵⁵Lr at a bombarding energy of 217MeV. The single-particle structure and decay properties were investigated using α, γ and electron spectroscopy. The ground-state spin and parity could be assigned for ²⁵⁵Lr (1/2-) and ²⁵¹Md (7/2-). States corresponding to...[Show more]
