Nuclear Tracks in Solids: Registration Physics and the Compound Spike
Observations of GeV heavy ion and MeV cluster-ion tracks in crystalline solids give us new insight into registration physics. Thermal and ion explosion spikes no longer compete; a 'compound spike' accounts for both. Ion explosion dominates for surface tracks (electronic sputtering). And there can also be transient plasma stopping in the bulk. For clusters there are 'vicinage effects' - both electronic and nuclear - which can influence track dimensions and structure. Displacement cascades in...[Show more]
