[en] Different aspects of the non-proliferation and safeguards system are criticized, not allowing the IAEA to have either organisation or the possibility to detect clandestine facilities or undeclared nuclear activities of Non-Proliferation Treaty States

[en] Effect of the coupling between the ground and the first excited monopole state in intermediate energy p-⁴He elastic scattering has been estimated using the breathing mode model and found to be important beyond the first diffraction minima. (author)

[en] The recent precise measurement of the neutral pion photoproduction on the proton near threshold seems to be inconsistent with the predictions of the low-energy theorems on photoproduction of pions. In this note, we have sought to resolve this problem, in the framework of an approximate SU(2)xSU(2) symmetry of the pion-nucleon dynamics, by incorporating the contribution from the nucleon matrix elements of the equal-time commutator between the divergence of the axial-vector current and the electromagnetic current, which was introduced earlier by Furlan et al. We find that a mean value of the non-strange quark mass m-circumflex=1/2(m_u+m_d)=(7+-2) MeV, leads to an estimate of the symmetry breaking terms compatible with experiment.

[en] Parity violating asymmetry in high energy proton-nucleon scattering has been studied using the Glauber theory and meson exchange potential model for weak interactions. By varying the weak interaction parameters within the allowed range, we find that it is possible to get the theoretical asymmetries to agree in sign with the observed ones in p-vector-H₂O scattering at 1.5 and 6.0 Gev/c but not in magnitude which always remains much smaller.

[en] The calculations for the neutrino absorption cross sections for supernova neutrinos in ⁴⁰Ar have been done in the local density approximation (LDA) taking into account Pauli blocking and Fermi motion effects. The renormalization of weak transition strengths in the nuclear medium and the effect of Coulomb distortion of the lepton produced in charged current reactions are taken into account. The expected event rates for electrons (positrons) have been calculated for a 3 kT liquid argon detector for a supernova occurring at 10 kpc from earth

[en] The present status of electroweak nucleon form factors and the N - Δ transition form factors is reviewed. Particularly the determination of dipole mass M_A in the axial vector form factor is discussed

[en] The Westinghouse Nb₃Sn Magnet for the Oak Ridge National Laboratory Large Coil Program (LCP) is currently well into the manufacturing phase. This paper identifies the manufacturing processes and development tasks for his unique, advanced coil

[en] We have fitted new parameter sets for finite and infinite nuclear system within the relativistic mean field theory (RMF). The contributions of isospin vector channel are incorporated on top of the non-linear Walecka and effective mean field motivated extended Lagrangian. This fitting is taken care within the minimization by using simulated annealing method (SAM). We discussed some more properties of finite and infinite nuclear system with these newly obtained parameters and compared with the well established effective mean field like NL3 and G2 interactions
