…capture (to produce isotopes of ytterbium), with some alpha and positron emission; the heavier isotopes decay primarily via beta decay, producing hafnium isotopes. Experiments at the Facility for Rare Isotope Beams have reported lutetium-190 in fragments of platinum-198 colliding with a carbon target…
