Spontaneous Radiation Bounds on Collapse Models: Recomputed Emission Rates for Germanium Detectors

This paper recomputes relative spontaneous-radiation rates for collapse models under the scaling with collapse rate and correlation length used in detector analyses, normalised to a stated reference point. At the conventional parameters the normalised rate is 1.00e-03 in the units adopted here; raising the collapse rate to 1e-10 per second raises the emission to 1.000e+03, while widening the correlation length to one micrometre lowers it to 1.000e-05. The inverse-square dependence on correlation length means radiation searches and interferometric searches probe complementary directions in parameter space, and neither alone closes the plane. All rates here are relative to the stated normalisation; absolute detector limits require the full spectral calculation. The study is simulated and computed from stated assumptions; it is not a measurement.
