摘要：
The ortho-positronium lifetime in ice in the range of temperature of 1 K below the melting point contains a component longer than the one determined in water. This work provides an experimental evidence of local ice melting owing to the energy deposited in the cluster of ionization products (blob) at the end of positron track. (C) 2014 Elsevier B.V.
