Single-particle kinetic energy spectra and two-particle small angle correlations of protons (p), deuterons (d) and tritons (t) have been measured simultaneously in 61A MeV Ar + Al, Sn and Sn collisions. Characteristics of the emission sources have been derived from a “source identification plot” (βsource–ECM plot), constructed from the single-particle(More)

From velocity-gated small-angle correlation functions the emission chronology can be deduced for non-identical particles, if the emission is independent. This is not the case for non-identical particles that originate from two-body decay of fragments. Experimental results may contain contributions from both independent emission and two-body decay, so care(More)
The experimental emission probabilities of complex fragments by low energy compound nuclei and their dependence upon energy and Z value are compared to the transition state rates. Intermediate-mass-fragment multiplicity distributions for a variety of reactions at intermediate energies are shown to be binomial and thus reducible at all measured transverse(More)
The aim of this prospective study was to assess the effectiveness in healing anal fissure (AF) of lacidipine, a calcium channel blocker with a better tolerability in comparison to other calcium antagonists. Twenty-one consecutive patients (16 women, 76.2%) with AF (16 chronic, situated posteriorly in 17 patients (81.0%), anteriorly in 4) with a mean age of(More)
The effects of the finite size of a liquid drop undergoing a phase transition are described in terms of the complement, the largest (but mesoscopic) drop representing the liquid in equilibrium with the vapor. Vapor cluster concentrations, pressure, and density from fixed mean density lattice gas (Ising) calculations are explained in terms of the complement(More)
