  The existence of a second bound state of PsH that is electronically stable
and also stable against positron annihilation by the normal 2gamma and 3gamma
processes is demonstrated by explicit calculation. The state can be found in
the 2,4So symmetries with the two electrons in a spin triplet state. The
binding energy against dissociation into the H(2p) + Ps(2p) channel was
6.06x10-4 Hartree. The dominant decay mode of the states will be radiative
decay into a configuration that autoionizes or undergoes positron annihilation.
The NaPs system of the same symmetry is also electronically stable with a
binding energy of 1.553x10-3 Hartree with respect to the Na(3p) + Ps(2p)
channel.
