  A number of bound states properties and the hyperfine structure of the
23S(L=0)-state in the Be atom are determined from the results of highly
accurate computations. The energies of the hyperfine structure levels for this
state are {\epsilon}(F=12) = -13725.635(7) MHz, {\epsilon}(F=32) = -5490.254(7)
MHz and {\epsilon}(F=52) = 8235.381(7) MHz, respectively. The hyperfine
structure splittings are {\Delta}12 = 8235.381(7) MHz and {\Delta}23 =
13725.635(7) MHz, respectively. The spectrum of low-lying (bound) triplet
states in the Be atom is briefly investigated.
