  The bound state spectrum of low-lying triplet states in the Be atom is
investigated. In particular, we perform accurate computations of various bound
triplet S, P, D, F, and G states in the four-electron Be atom. For the 23S(L=0)
state in the Be atom we determine the hyperfine structure and a number of bound
states properties by using results of highly accurate computations. The
energies of the hyperfine structure levels for this state are {\epsilon}(F=12)
= -13725.927(7) MHz, {\epsilon}(F=32) = -5490.371(7) MHz and {\epsilon}(F=52) =
8235.556(7) MHz, respectively. The observed hyperfine structure splittings for
the the 23S(L=0) state in the 9Be atom must be {\Delta}12 = 8235.556(7) MHz and
{\Delta}23 = 13725.927(7) MHz, respectively.
