“…Neutron-deficient hassium were produced in so-called "cold" fusion reactions using the reactions 208 Pb( 56 Fe, 1n) 263 Hs [2,3], 207 Pb( 58 Fe, 1n) 264 Hs, and 208 Pb( 58 Fe, 1n) 265 Hs [5]. The more neutron-rich 266 Hs, 267 Hs, and 269 Hs were observed for the first time as daughters of 270 Ds, 271 Ds, and 277 Cn produced in the cold fusion reactions 207 Pb( 64 Ni, 1n) [6], 208 Pb( 64 Ni, 1n) [7][8][9], and 208 Pb( 70 Zn, 1n) [11][12][13], respectively.…”
