It will tell us a lot about a neutron star.
” Subtracting the known proton radius revealed a neutron skin 0.33 millionths of a nanometer thick, give or take about 50%”
“The PREX measurement suggests that the neutron skin of lead-208 is twice as thick as more-precise but model-dependent methods indicate.”
Hmm, so the measurement suggests it is twice as thick as previous measurements, but they estimate margin of error at 50%? Interesting stuff, but I can’t get too excited about the results with those numbers.
” There’s a possibility to set your skin a-tingling.”
50%, more or less, it does, it really does.
