A model is proposed for the spectrum of $\Lambda$ hypernuclei based on the$u(3)\times u(2)$ Lie algebra, in which the internal degrees of freedom of thespin-1/2 $\Lambda$ particle are treated in the Fermionic $u(2)$ scheme, whilethe motion of the hyperon inside a nucleus is described in the Bosonic $u(3)$harmonic oscillator scheme. Within this model, a simple formula forsingle-particle energies of the $\Lambda$ particle is obtained from the naturaldynamical symmetry. The formula is applied to the experimental data on thereaction spectroscopy for the $^{89}_\Lambda$Y and $^{51}_\Lambda$Vhypernuclei, providing a clear theoretical interpretation of the observedstructures.
