Abstract
Production cross-sections of the isotope 256Lr in the 249,250,251Cf +11B, 243Am +18O, and 248Cm +14N reactions were measured using a He/KCl gas-jet transport system and a rotating wheel α-particle detection apparatus. The α-particle energy of 256Lr was distributed from 8.3 to 8.7 MeV and its half-life, T1/2, was measured to be 28 ± 1 s. The maximum cross sections in the 249Cf(11B, 4n)256Lr and 243Am(18O, 5n)256Lr reactions were determined to be 122 ± 36 nb at the beam energy of 63 MeV and 26 ± 7 nb at 96 MeV, respectively. In the 248Cm(14N, 6n)256Lr reaction, the cross section was measured to be 27 ± 10 nb at 91 MeV.
