Abstract

Angular and energy distributions are reported for ⁴He in correlation with ^1,2,3H and ⁴He in the reaction 337 MeV ⁴⁰Ar+^natAg. Comparisons are made to a statistical model that includes emitter. Energy spectra important barrier reductions compared to those for cold nuclei, ≈25%, 12%, 8% and 0 for ¹H, ⁴He, ²H and ³H respectively. Emitter deformation alone cannot give an explanation. A transitory nuclear stratosphere is suggested with proton emission favored from its fringes of lowest density.
