The suggestion is made that the excited state of the $^3 H$ nucleus found out recently in the reaction $H$ ($^6 He$,$\alpha$) ({\it Pis'ma JETPh\/} {\bf 59} (1994) 301) has spin and parity $1/2^+$ and the same configuration that the ground one of $^6 He$. An amplitude of electromagnetic transition to the triton ground state is strongly suppressed, therefore the excited state cannot be detected in radiative capture of neutrons by deuterons. It is shown that in an elastic nd-scattering a resonance associated with the exited state may be absent due to the destructive interference of potential and resonant scattering phases.
