A new avenue in the search for <i>CP</i> violation:Mössbauer spectroscopy of <sup>227</sup> Ac
This work proposes a new avenue in the search for CP-violating odd-electric
and even-magnetic nuclear moments. A promising candidate to find such moments
in the ground state is the quadrupole-deformed and octupole-correlated nucleus
227-actinium. In this nucleus, the 27.4-keV ~transition that connects the
parity-doublet partner and the ground state is perfectly suited
to apply the sensitive technique of recoil-free selfabsorption, commonly known
as M\"ossbauer spectroscopy. In this experimental approach, the lifetime of the
upper parity-doublet partner allows an estimate of the lower limit of
= eV for the
achievable energy resolution to be made. This resolution must be exceeded by
the interaction of a CP-violating moment and the corresponding multipole moment
of the field distribution in the lattice. This work presents the first ideas
for patterns caused by CP-violating moments on the expected quadrupole
splitting and nuclear Zeeman effect.Comment: 9 pages, 4 figure
A new avenue in the search for CP violation: Mössbauer spectroscopy of 227Ac
This work proposes a new avenue in the search for CP-violating odd-electric and even-magnetic nuclear moments. A promising candidate to find such moments in the ground state is the quadrupole-deformed and octupole-correlated nucleus 227-actinium. In this nucleus, the 27.4-keV E1 transition that connects the 3/2+ parity-doublet partner and the 3/2− ground state is perfectly suited to apply the sensitive technique of recoil-free selfabsorption, commonly known as Mössbauer spectroscopy. In this experimental approach, the lifetime of the 3/2+ upper parity-doublet partner allows an estimate of the lower limit of ΔE = 2 · Γγ = 23.7(1) × 10−9 eV for the achievable energy resolution to be made. This resolution must be exceeded by the interaction of a CP-violating moment and the corresponding multipole moment of the field distribution in the lattice. This work presents the first ideas for patterns caused by CP-violating moments on the expected quadrupole splitting and nuclear Zeeman effect.Output Status: Forthcomin
