Abstract
An investigation of the decay of was performed using an ultra-low-background twin Frisch-grid ionization chamber (TF-GIC). Four natural samarium samples were produced using pulsed laser deposition in ultrahigh vacuum. The abundance of the isotope was measured using inductively coupled plasma mass spectrometry. A combined half-life value for of yr was measured. A search for the decay into the first excited state of has been performed using spectroscopy, resulting in a lower half-life limit of yr (at 90% C.L.).
