(19760301)The pion mass extrapolation corrections to the Adler term in pi 0 to 2 gamma are determined. These are substantial and obviate the need for colour.

(19820901)A model is proposed for the 2+ first excited state in 12C in which the dominant configurations outside the p shell are assumed to come from mixing with an 'idealised' isoscalar giant quadrupole resonance. A small admixture ...

(19881101)Gamma rays and internal conversion electrons have been measured in 100Ru following thermal neutron capture using germanium and highresolution electron spectrometers respectively. A decay scheme of lowlying levels has ...

(19750620)The four particle transfer 11B(7Li, t) reaction has been studied at 12 MeV incident energy. Triton angular distributions corresponding to 18 energy levels in 15N below 10.8 MeV excitation are presented. Those exhibiting ...

(19830201)Values of sigma R and sigma T are obtained from an opticalmodel analysis of 12C12C elastic scattering data between 6 and 85 MeV/A. They confirm the general trends predicted by DeVries and collaborators (1980, 1981) but ...

(19840601)The spintransfer coefficient Kyy'(0 degrees ) has been measured for the reaction 12C(p,n)12N at Ep=65 MeV using the neutron double scattering technique. Microscopic DWBA calculations with the M3Y effective interaction ...

(19850401)A cluster model is used to calculate the energies of those states in 17F and 17O which have a trinucleon14N clustercore structure. The noncentral terms in the clustercore potential are deduced phenomenologically and ...

(19770801)The masses of charmed baryon states are predicted under the hypothesis of 15plet dominance of SU(4) symmetry breaking, the analogue of octet dominance of SU(3) symmetry breaking. The breaking of SU(3) is completely ...

(19780201)The observed asymmetry in the angular distribution of the 16O( gamma ,n)15O reaction above the giant resonance region is investigated. The existence of electric dipole (with T=1) and electric quadrupole (with T=0 and 1) ...

(19750905)The 25Mg(3He, alpha )24Mg reaction has been studied at an incident energy of 18 MeV. Fortysix states in 24Mg have been identified up to an excitation of 12.051 MeV including a new state at 9.650 MeV. Absolute spectroscopic ...

(19811101)Practical QCD is an effective field theory in that unexcited heavy quarks are decoupled from the theory. To predict effects dependent on the heavy quarks one needs the RG invariants of the effective QCD in which they are ...

(19770401)Accepting the hypothesis that psi (3.1) is a bound state of the charmed quark (p') and its antiquark (p'), the psi (3.1) p'p' coupling constant is evaluated by applying the technique of dimensional regularization. The value ...

(19771001)Absolute angular distribution measurements have been made at 14.1 MeV for the proton pickup reactions 35Cl(n,d)34S ground state and 34S* (2.127 MeV), 37Cl(n,d)36S ground state, and 36Ar(n,d)35Cl ground state and 35Cl* ...

(19881101)A measurement of the absolute differential cross sections for the reaction 3He(d,3He p)n at Ed=23.083 MeV was performed. The particular kinematical configuration allowed for the neutronproton finalstate interaction at ...

(19790401)The 18O(t,p) reaction has been used to locate 0+ and 2+6p2h levels at 4456 and 5304 keV, respectively, in 20O. Excitation energies and (t,p) strengths are in good agreement with this identification. Results for all other ...

(19810501)A threestate isospinmixing model is fitted to available data on pion scattering and nucleon pickup relevant to the 4 states of 16O at 17.79, 18.98 and 19.80 MeV. An excellent fit to all data is obtained, and the state ...

(19750401)Measurements have been made of the differential cross sections for 3He scattering from the samarium isotopes Sm 144, 148, 150, 152, 154 at 53.4 MeV. An optical model analysis has been performed to compare with similar ...

(19870701)An equation for the wavefunction of a threecorrelated fermion cluster is obtained from a variational method starting from an explicit expression that takes into account the complete antisymmetrisation between this correlated ...
