We have studied the stability of mixed 3He/4He clusters in L ¼ 0 and L ¼ 1 states by the diffusion Monte Carlo method, employing the Tang-Toennies-Yiu (TTY) He-He potential. The clusters 3He4HeM (L ¼ 0, S ¼ 12) and 3He2 4HeM (L ¼ 0, S ¼ 0) are stable for M >1, while to bind two 3He in a triplet state the minimum number of 4He is four. Considering clusters with three 3He, 3He3 4He4 is the smallest stable system in the L ¼ 1 state, while 3He3 4He8 is the smallest stable system in the L ¼ 0 state.

Abstract
We have studied the stability of mixed 3He/4He clusters in L ¼ 0 and L ¼ 1 states by the diffusion Monte Carlo method, employing the Tang-Toennies-Yiu (TTY) He-He potential. The clusters 3He4HeM (L ¼ 0, S ¼ 12) and 3He2 4HeM (L ¼ 0, S ¼ 0) are stable for M >1, while to bind two 3He in a triplet state the minimum number of 4He is four. Considering clusters with three 3He, 3He3 4He4 is the smallest stable system in the L ¼ 1 state, while 3He3 4He8 is the smallest stable system in the L ¼ 0 state.
