General Comments:

Isotope shift (relative to 214Ra)=-53634 15 MHz (1988Ah02). The change in the nuclear mean square charge radius=1.67 17, was calculated in 1988Ah02 from the experimental value of the isotopic shift.

See 1988Ah02 for deformation parameter deduced from the measured isotope shift. See 1975Iv03, 1982Du16, 1982Le19, 1983Ro14, 1984Na22, for theoretical calculations of equilibrium deformations.

See 1975Iv03 and 1983Ro14 for theoretical quadrupole and hexadecapole moments.

See 1991Eg01 for calculation of K=0- octupole-vibrational level energy, and for B(E1) and B(E3) values. See 1988Ri07 for calculated values of B(E2; 2+ to 0+).

See 2010Ro08 and 2005Bo18 for calculation of octupole states and transition strengths.

Measured mass excess (Δm=34518 keV 12) using a Penning trap mass spectrometer (2008We02).

Calculated excitation energy of first Jπ=2+ state (2008Bi03).
