    Research output: Contribution to journalArticlepeer-review


    The blackbody radiation shift of the Al+ 3s2 1Se 0 ? 3s3p 3Po 0 clock transition is evaluated. The polarizabilities of the two states are determined by means of configuration interaction calculations in conjunction with oscillator strength sum rules. The ground state polarizability was 24.14 �0.12 a.u. while the metastable state polarizability was 24.62 �0.25 a.u. The derived frequency shift at 300 K was ??= -0.0042 �0.0032 Hz. Some auxiliary sum rules are evaluated that allow for the conversion of a finite frequency polarizability difference to a static polarizability difference. � 2009 EDP Sciences, SIF, Springer-Verlag Berlin Heidelberg.
