Extended Data Fig. 7: Significance and cross-sectional ratio profile likelihood.
From: Direct observation of the Migdal effect induced by neutron bombardment
a, Likelihood function for the significance test of the Migdal effect. b, likelihood function for the number of Migdal effect events. The upper and lower limits corresponding to a standard deviation are \({n}_{{ll}}=24.88\), \({n}_{{ul}}=60.89\), respectively.
