We measured the vapour pressure of several DNA and RNA bases—uracil, adenine, guanine, thymine and cytosine—in the 300–450 K range. In each case the sample mass loss rate was measured as function of temperature with a simple setup consisting of

Calculation of three-body reactions with Coulomb interaction
Autor: J. R. Brinati, M. H. P. Martins
Publikováno v: Physical Review C. 46:1607-1611
Three-body nuclear reactions with Coulomb interaction are treated using the formalism of Alt, Sandhas, and Ziegelmann when two of the three particles are charged. Aspects of the numerical calculation are discussed and its difficulties are pointed out

Three-body calculation of deuteron-induced-stripping reactions
Autor: J. R. Brinati, M. H. P. Martins
Publikováno v: Canadian Journal of Physics. 69:16-23
Differential cross sections for the reactions (d,p) and (d,n) are calculated, considering a three-body system with Coulomb interaction and total energies of the system under the break-up threshold. The method used to describe this system is the one p

Absolute total destruction cross sections of B and Al small anionic clusters impinging onN2targets
Autor: S. D. Magalhães, Fabio Zappa, João Alberto Martins Pereira, M. H. P. Martins, Wilma M S Santos, A. L. F. de Barros, Adir M Luiz, N. V. de Castro Faria, L. F. S. Coelho
Publikováno v: Physical Review A. 67
Absolute total destruction cross sections of B{sub n}{sup -} (n=1,2) and Al{sub n}{sup -} (n=1-4) clusters colliding with N{sub 2} were measured for relative velocities in the interval 0.2-1.0 a.u. All cross-section curves may be described as a singl
