  The radium atom is a promising system for studying parity and time invariance
violating weak interactions. However, available experimental spectroscopic data
for radium is insufficient for designing an optimal experimental setup. We
calculate the energy levels and transition amplitudes for radium states of
significant interest. Forty states corresponding to all possible configurations
consisting of the $7s$, $7p$ and $6d$ single-electron states as well as the
states of the $7s8s$, $7s8p$ and $7s7d$ configurations have been calculated.
The energies of ten of these states corresponding to the $6d^2$, $7s8s$,
$7p^2$, and $6d7p$ configurations are not known from experiment. Calculations
for barium are used to control the accuracy.
