Two-particle rapidity correlations between relativistic particles in central collisions of Au nuclei in emulsion at 11.6 A GeV/c
It is shown that in central collisions of Au nuclei with heavy
emulsion nuclei at 11.6 GeV/c two-particles pseudorapidity correlations for
produced particles in terms of correlation functions demonstate predominantly
long-range behaviour in contrast to nucleon-nucleon interactions. The
experimental data are compared with calculations based on the FRITIOF-M model
and the model of independent emission of particles.Comment: 5 pages, 3 figure
Asymptotic normalization coefficients (nuclear vertex constants) for and the direct astrophysical S-factors at solar energies
A new analysis of the precise experimental astrophysical S-factors for the
direct capture reaction [A.J.Junghans et al.Phys.Rev. C
68 (2003) 065803 and L.T. Baby et al. Phys.Rev. C 67 (2003) 065805] is carried
out based on the modified two - body potential approach in which the direct
astrophysical S-factor, , is expressed in terms of the
asymptotic normalization constants for and two additional
conditions are involved to verify the peripheral character of the reaction
under consideration. The Woods-Saxon potential form is used for the bound
()- state wave function and for the - scattering wave function.
New estimates are obtained for the ^{\glqq}indirectly measured\grqq values of
the asymptotic normalization constants (the nuclear vertex constants) for the
and at E 115 keV, including =0. These
values of and asymptotic normalization constants have been used for
getting information about the ^{\glqq}indirectly measured\grqq values of the
wave average scattering length and the wave effective range parameters
for - scattering.Comment: 27 pages, 6 figure
