    "abstract": "We make a comparative study of hard x-ray emission from 15 $\\mu$m methanol\nmicrodroplets and a plain slab target of similar atomic composition at similar\nlaser intensities. The hard X-ray yield from droplet plasmas is $\\simeq$ 35\ntimes more than that obtained from solid plasmas. A prepulse that is about 10ns\nand about 5% of the main pulse is essential for hard x-ray generation from the\ndroplets.\n  A hot electron temperature of 36 keV is measured from the droplets at\n8$\\times10^{14}$ W cm$^{-2}$; three times higher intensity is needed to obtain\nsimilar hot electron temperature from solid plasmas with similar composition.\nWe use 1D PIC simulation to obtain qualitative correlation to the experimental\nobservations.",
