    "abstract": "We study the formation of an entangled state in a one-dimensional chain of\nthree nuclear spins system which interact weakly through the Ising type of\ninteraction and taking into account first and second neighbor interactions. We\ncan get this entangled state using two pulses ($\\pi/2$ and $\\pi$ pulses), and\nwe study the efficiency of getting this entangled state as a function of the\nratio of the second neighbor interaction coupling constant to the first\nneighbor interaction coupling constant ($J\u0027/J$). We found that for $J\u0027/J\\ge\n0.04$, the entangled state is well defined.",
