Final inversion S3(2tp) for sin-squared pulse as a function of pulse area θ. The pulse area is in multiples of Π. The excitation is on-resonance and φ = 0. (a) np= 10, (b) np= 3, (c) np= 2, and (d) np= 1. Solid curve: N = 109cm−2, dotted curve: N = 3 × 1011cm−2, dashed curve: N = 5 × 1011cm−2, and dot-dashed curve: N = 7 × 1011cm−2.
