  I propose a new paired-wavefunction with a parameter that continuously
interpolates from the 1D Jastrow-product to the Majumdar-Ghosh
dimer-wavefunction appropriate for the frustrated Heisenberg $S = 1/2$
antiferromagnet. This spin paired-state constructed in $S_z$ basis is an
alternative to the well-known resonating-valence-bond basis state for
describing the $S = 0$ ground-state with no apparent long-range spin order.
Some numerical evidences are presented.
