GABRIELA setup for nuclear spectroscopy of the transfermium element isotopes at the VASSILISSA separator
Résumé
The JINR (Dubna)-IN2P3 (France) Collaboration project aimed at the alpha, beta, gamma spectroscopy of the transfermium element isotopes using heavy-ion beams of the U-400 cyclotron and the modernized recoil separator VASSILISSA was launched at Dubna. During the first full-scale experiment in September-October 2004, nobelium and lawrencium isotopes produced in the Ca-48 + Pb-207,Pb-208 -> No-255,No-256* and Ca-48 + Bi-209 -> Lr-257* reactions were studied
