    "abstract": "The dynamics of vibrational wave packets excited in K$_2$ dimers attached to\nsuperfluid helium nanodroplets is investigated by means of femtosecond\npump-probe spectroscopy. The employed resonant three-photon-ionization scheme\nis studied in a wide wavelength range and different pathways leading to\nK$^+_2$-formation are identified. While the wave packet dynamics of the\nelectronic ground state is not influenced by the helium environment,\nperturbations of the electronically excited states are observed. The latter\nreveal a strong time dependence on the timescale 3-8 ps which directly reflects\nthe dynamics of desorption of K$_2$ off the helium droplets.",
