Abstract

¹²⁹Nd was produced by irradiation of an enriched target of ⁹⁶Ru with a ³⁶Ar beam and studied by using a helium-jet fast tape transport system in combination with X- and - coincidence measurements. A 2.6s isomer of ¹²⁹Nd was observed for the first time and tentatively proposed to be the configuration of 1/2[411].
