The confirmation of such a neutrinoless decay would be historic, requiring updates to the Standard Model of Particle Physics. (phys.org)

The measured α -decay energy of 6880 ± 10 keV allowed the excitation of the πh 11 / 2 state in 160 Re to be deduced as 166 ± 14 keV. (jyu.fi)

During the past half one or more slowly decaying components in addition to the century, a diverse array of techniques has therefore been inertial decay (which is not always resolved) and a fast diffusive recruited to the challenging task of quantitatively characterizing, decay of a few picoseconds (corresponding to the 1 ps under physiological solution conditions, the motions of water component of the free probe).
