  The symmetric components of the spatial part of $S$- and $D$- states'
wavefunctions for triton $(^{3}H)$ are investigated utilizing semiclassical
expansion (in the powers of $\hbar$). Analysis of the diagonalized Hamiltonian
reveals the existence of two different mass states within the ground state of
triton. We have solved the coupled differential equations for the two admixed
states $^{2}S_{1/2}$ and $^{4}D_{1/2}$ owing to tensor interactions exploiting
classical WKB-theory using phenomenological Feshbach-Pease potentials. The
relative probability of the $D$-state is found to be in good agreement with the
experimentally inferred value (4 - 5 \%).
