Gas phase production of NHD2 in L134N [PDF]

, 2001
We show analytically that large abundances of NH2D and NHD2 can be produced by gas phase chemistry in the interiors of cold dense clouds. The calculated fractionation ratios are in good agreement with the values that have been previously determined in ...

Gluon production, cooling and entropy in nuclear collisions [PDF]

, 1997
We study the cooling (heating) of a glue-parton gas due to production (destruction) of particles and determine the associated production of entropy. We incorporate sharing of the system energy among a changing number of particles.
