What it covers
CERN INTC proposal INTC-P-410: search the chart for β or electron-capture transitions with the lowest possible decay energy, as candidates for a direct neutrino-mass measurement.
Methods and setup
ISOLTRAP Q-value measurements of selected parent-daughter pairs, later including the PI-ICR method once it was online.
Why it matters
A neutrino-mass calorimeter only works if almost all of the decay energy sits near zero. This proposal is the beam-time frame for the ¹³¹Cs, ²⁰²Pb, ¹⁵⁹Dy, and ¹⁷⁵Hf Q-value programme.
