Isotopic tuning of the 2 3P0-2 1S0 and 2 3P1-2 1S0 transition energies in He-like ions for future parity-nonconservation experiments

Crossings of opposite-parity levels in He-like ions for particular values of the atomic number Z offer excellent conditions for precise experimental tests of parity-nonconservation (PNC). Such tests may be performed by inducing, through intense lasers, transitions that are only allowed in presence o...

Description
Summary:Crossings of opposite-parity levels in He-like ions for particular values of the atomic number Z offer excellent conditions for precise experimental tests of parity-nonconservation (PNC). Such tests may be performed by inducing, through intense lasers, transitions that are only allowed in presence of PNC. Several spectroscopy experiments have been proposed in the past, but only now, with the advent of high-intensity laser facilities (e.g. PHELIX at GSI or POLARIS at Jena), their feasibility is within reach. In this paper, we use relativistic many-body perturbation theory (RMBPT) to calculate accurately the crossing conditions of the excited levels (1s2s) 1S0 and (1s2p) 3P0 and of (1s2s) 1S0 and (1s2p) 3P1 in intermediate and heavy He-like ions. Moreover, we show the dependence of the energy splittings upon the choice of the nuclear isotope.
Item Description:Im Titel ist die Ziffer 3 bei 3P0 und bei 3P1 und die Ziffer 1 bei 1S0 jeweils hochgestellt, die Ziffer 0 überall und die Ziffer 1 bei 3P1 jeweils tiefgestellt
