Abstract.The decay of odd-mass mendelevium isotopes ( A = 247-255) has been studied by means of α-γ spectroscopy. Strong evidence for a small α branch in the decay of 253Md was found. γ lines in coincidence with α-decays of 247, 249, 251, 253Md have been observed for the first time. Levels in the einsteinium daughter nuclei were assigned on the basis of α-γ coincidence measurements. An energy systematics of the 7/2-[514] Nilsson level could be established, showing a correlation with the…

Nuclear structure investigations in the region of superheavy nuclei

Radioactive decay from the ground state or isomeric states has been investigated for a series of nuclei in the region of Z = 100–106 by means of α–γ—or evaporation residue-(γ, conversion

Isomeric states in 253No and 253Fm

Abstract.Nuclear structure and decay of isomeric states in 253No were investigated. The isotope was produced by the reaction 48Ca + 207Pb . The excitation energy of the known single-particle isomeric

Spectroscopy and single-particle structure of the odd- Z heavy elements 255Lr, 251Md and 247Es

Abstract.The odd-Z isotope 255Lr, its daughter 251Md and grand-daughter 247Es were studied in two experiments performed at GANIL and the University of Jyväskylä. The 255Lr nuclei were produced using

Nuclear isomers in 259Sg and 255Rf

The production and radioactive decay of 259Sg and its daughter products were investigated using α-decay spectroscopy and spontaneous-fission measurements. The isotope was produced in the

Studies of neutron-deficient mendelevium isotopes at SHIP

The radioactive decay of the isotopes 247Md , 246Md and their daughter products was investigated by means of $ \alpha$ -$ \alpha$ and $ \alpha$ -$ \gamma$ coincidence spectroscopy. The isotopes were

GSI experiments on synthesis and nuclear structure investigations of the heaviest nuclei

Abstract.Isotopes of elements up to Z = 113 have been synthesized using medium heavy projectiles and target nuclei around doubly magic 208Pb. Synthesis of still heavier elements in reactions of 48Ca

Study of 242−248Cm isotopes in the projected shell model framework

The projected shell model framework is employed to study the band spectra in 242−248Cm isotopes. The present calculations reproduce the available experimental data on the yrast bands. Besides this,
