The nuclear structure of 24Na and some remarks on the nuclear structure of 25Mg
(Elsevier, 1964)
The experimental data on the 23Na(d, p)24Na reaction at Ed = 7.8 MeV reported in a previous paper 1) (referred to as I) are used for a tentative interpretation of the even parity levels of 24Na at low excitation. Comparison ...
Measurements of d, p[gamma] directional correlations in 20F
(Elsevier, 1965-09)
The reaction 19F(d, p[gamma])20F was used to measure the directional correlations of the proton groups in coincidence with subsequent gamma radiations produced in de-excitation of the 2.05, 1.31, 1.06, 0.99 and 0.65 MeV ...
Simple shell-model expressions for coulomb energies
(Elsevier, 1968-06-24)
It is shown that the main n-T dependent terms of the Coulomb energy have the same general form in the Wigner supermultiplet scheme as in the low seniority limit of the j-j coupling scheme of the shell model.
Five-dimensional quasi-spin the n, T dependence of shell-model matrix elements in the seniority scheme
(Elsevier, 1967-09-29)
The five-dimensional quasi-spin formalism is used to factor out the n, T dependent parts of shell-model matrix elements in the seniority scheme and derive reduction formulae which make it possible to express matrix elements ...
Generalized seniority for favored J [not equal to] 0 pairs in mixed configurations
(Elsevier, 1969-11-03)
By assigning a pseudo-spin and pseudo-orbital angular momentum (b-spin and c-spin) to the single-particle states in a mixed configuration of identical nucleons, it is possible to classify as B = 0 objects both the favored ...
The lowest T = 0 states in the odd N = Z nuclei with A > 40
(Elsevier, 1962)
There is indication that the lowest T = 0 and T = 1 states are inverted not only in Cl34 but also in Sc42, V46, Mn50 and Co54. Isomerism in all these nuclei is likely.
SU3 recoupling and fractional parentage in the 2s-1d shell
(Elsevier, 1965-02)
Explicit algebraic expressions have been calculated for both the SU3 Wigner coefficients and the SU3 Racah coefficients which are of particular interest in the recoupling problem involving 2s-1d shell nucleons and basis ...
Gamma ray image characteristics in sodium iodide slabs
(Elsevier, 1969-06-01)
A Monte Carlo calculation has been made of the effects of detector scattering on the gamma ray imaging properties of sodium iodide slabs. All interactions within the detector were assumed to contribute to the image. A ...
Two-group reactor noise analysis by Langevin's technique
(Elsevier, 1968-11)
Langevin's technique is applied to two energy group space independent reactor model. Detection statistics and fluctuations in production and decay rate of delayed neutron precursors are also taken into account. Expressions ...
