Precision measurement of the electric quadrupole moment of 31Al and determination of the effective proton charge in the sd-shell

M. De Rydt, G. Neyens, K. Asahi +20

he electric quadrupole coupling constant of the 31Al ground state is measured to be nu_Q = |eQV_{zz}/h| = 2196(21)kHz using two different beta-NMR (Nuclear Magnetic Resonance) tech…
