Abstract
The novel universal technique for impurities embedding directly into solid He we recently $elaborated^{a}$ allows to acheive the guest particles concentrations as high as $10^{19} cm^{-3}$ (as small clusters suspended in a solid) and about $10^{16} cm^{-3}$ (as solitary isolated molecules or atoms) under a sample growth rate up to 3 mm per minute. Contrary to the liquid He droplets technique we can investigate the temperature and pressure dependecies, whereas the procedure of a sample preparation and replacement is more simple than for matrix-isolation by $p-H_{2}$. The promises for spectroscopic applications of the new matrix and the first experimental results will be discussed.
