(1993-11-01)The complete conversion-electron spectrum has been analysed with an electrostatic spectrometer at 6.5 eV instrumental resolution. The transition energy of 9396(3) eV and the E2 admixture parameter mod delta (E2/M1) mod ...
-
(1989-02-01)Subsequent to earlier analyses (1989) of elastic and inelastic scattering of polarised protons in terms of the optical and collective models a description of the reactions 116Sn (p,p') and 124Sn(p,p') is presented in terms ...
-
(1989-05-01)The authors have proposed a nonet symmetry breaking model to account for the observed branching ratios B(Ds+ to eta pi +) and B(Ds+ to eta ' pi +). Other consequences of this model are explored. They find that the branching ...
-
(2000-08-01)We propose a model based on Glauber-type scattering incorporated with quantum molecular dynamic model to describe proton-nucleus and nucleus-nucleus collisions at high energy ( 600 MeV) in a unified way. It is found that ...
-
(1995-03-01)The debate concerning the manner in which cosmic rays are accelerated is a continuing one but shocks associated with supernova remnants (SNR) are strong theoretical favourites, at least at energies below 1014 eV. Experimental ...
-
(2000-06-01)Non-relativistic potential models are considered of the pure power V(r) = sgn(q) rq and logarithmic V(r) = ln (r) types. It is shown that, from the spectral viewpoint, these potentials are actually in a single family. The ...
-
(1999-02-01)Strange particles produced in S-Au/W/Pb 200 A GeV and Pb-Pb 158 A GeV reactions are described invoking final hadronic phase space in thermal equilibrium, but allowing chemical nonequilibrium. Several sets of statistical ...
-
(1995-12-01)Our earlier calculations of 1976-77 and their later extensions are reviewed to show that the reactions used in the recent synthesis of the Z=110 element with masses A=269 and 271 at GSI had been previously proposed by Gupta ...
-
(1996-06-01)The charge asymmetry of W-bosons produced in collisions has been measured using 72 439 and decays recorded by the CDF detector during the 1992 - 93 and 1994 - 95 Tevatron collider runs. Preliminary results on the Drell ...
-
(1989-04-01)The energy dependence of the ion-ion reaction cross section has been investigated using the eikonal approximation to study the effects of the Pauli blocking and surface contribution to the optical potential. This leads to ...
-
(2000-04-01)An approximate analytic expression of the eikonal phase for the potential in the form of the symmetrized Fermi function is derived and compared with that obtained by exact calculations. It is shown to be successfully applied ...
-
(1990-01-01)Conversion electron and photon measurements with the electrostatic and HPGe spectrometers, respectively, proved the existence of the 7.133+or-0.010 keV transition in 160Ho. The conversion intensity ratios for ten outer ...
-
(2000-05-01)We review the production of charm and bottom quarks in two-photon collisions at e+e- colliders. The next-to-leading order QCD predictions for total cross sections and differential distributions are compared with ...
-
(1997-07-01)We show that the dynamics of the quark - gluon plasma is such that during hadronization the creation of hybrids will predominate over the creation of mesons, giving a novel signature of the existence of QGP. At T = 0 the ...
-
(1999-02-01)With the advent of the relativistic heavy ion collider (RHIC) at Brookhaven National Laboratory, heavy ion physics will enter a new energy regime. The question is whether the signatures proposed for the discovery of a phase ...
-
(1990-07-01)The K-electron capture probability in the decay of 167Tm for the first-forbidden transition 1/2+ to 3/2- was measured using the sum-coincidence method and employing a hyper-pure Ge system. The PK value is found to be ...
-
(1992-10-01)The author reviews recent lattice calculations of the form factors of semileptonic D decays, and of the decay constants of B and D mesons (fB and fD). Prospects for future computations are also discussed.
-
(1997-10-01)Solving microscopic Landau - Vlasov transport equations we focus on specific features associated with the fusion - fission dynamics. For mass-symmetric reactions we observe the formation of long-living deformed nuclear ...
-
(1991-11-01)The gamma d to d pi 0 process asymmetries for linearly polarized photons Sigma and vector polarized deuterons T were calculated in terms of impulse approximation (IA). The IA is based on the factorization of the isovector ...
-
(1991-12-01)New detectors operated at temperatures in the millidegree range offer the possibility for detecting radiation of nuclear origin with improved energy resolution and energy threshold. Basic features of two types of such ...
