Description

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]

dc.description.abstractThe 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 the 7/2+[633], 7/2-[514] and 1/2-[521] Nilsson orbitals were observed. Results are compared to experimental data obtained in neighbouring isotopes and to Hartree-Fock-Bogoliubov calculations using the Skyrme interaction SLy4 and a density-dependent pairing interaction. The position of the 1/2-[521] orbital from the spherical 2f 5/2 shell is discussed.
