Protolytic equlibria of bromazepam [PDF]

Journal of the Serbian Chemical Society, 2002
The protolytic equilibria of bromazepam, an ampholyte sparingly soluble in water, in homogeneous and heterogeneous systems were studied in the pH range 0–14 at 25ºC and at ionic strength of 0.1 mol/dm3 (NaCl).

Two-proton correlation functions for equilibrium and non-equilibrium emission

Physics Letters B, 1990
Abstract Two-proton correlation functions are compared for equilibrium and non-equilibrium emission processes investigated, respectively, in “reverse kinematics” for the reactions 129 XE+ 27 Al and 129 Xe+ 122 Sn at E A = 31 MeV and in “forward kinematics” for the reaction 14 N+ 197 Au at E A = 75 MeV . Observed differences in
