Pairing fluctuations and gauge symmetry restoration in rotating superfluid nuclei
Rapidly rotating nuclei provide us good testing grounds to study the pairing
correlations; in fact, the transition from the superfluid to the normal phase
is realized at high-spin states. The role played by the pairing correlations is
quite different in these two phases: The static (BCS like mean-field)
contribution is dominant in the superfluid phase, while the dynamic
fluctuations beyond the mean-field approximation are important in the normal
phase. The influence of the pairing fluctuations on the high-spin rotational
spectra and moments of inertia is discussed.Comment: 14 pages, 5 figures, a contribution to the book "50 Years of Nuclear

Magnetic Properties of Precession Modes Built on High-K Multi-quasiparticle States in ^{178}W
We present an example that shows that the random phase approximation
performed on high-K multi-quasiparticle configurations leads to a rotor picture
by calculating excitation energies and magnetic properties of ^{178}W. Then we
deduce the effective g_R of the high-K rotors and compare it with that of the
low-K one.Comment: 6 pages, 3 figures, Prog. Theor. Phys., accepte
Heuristic quantization of the cranking model
We propose a simple and systematic method to quantize the cranking model and
to calculate the matrix elements of intrinsic operators entering the
generalized intensity relations. An example of the application is given to show
the Coriolis coupling effects for B(E3) values of the 3- octupole states in Gd
isotopes.Comment: 2 pages, Latex, using epsf.sty, 1 postscript figure Talk given at the

Household Structure in Early Nineteenth Century Ireland
In this article, the author proposed the hypothesis that the nuclear family based on the nuclear
family system was predominant in early nineteenth century Ireland. However, the stem family
must also have existed. The author assumed that such stem families were supported by family
conditions and could be explained by a life cycle in the nuclear family system.
We divided the subjects of survey ground into 3 areas in consideration of economic regionality,
namely regarded Meath and King’s as the first region, Cavan and Fermanagh as the second
region, and Galway as the third region and has verified the proposed hypothesis based on the
records of the 1821 census returns.
In Meath and King’s, it can be said that the facts that the compound family households was
predominant among large landholding farmers and that the simple family households was
predominant among laborers reflected the family strategies behind each household type.
In Cavan and Fermanagh, people adopted the family strategy of manufacturing linen as weavers
and spinners. This family strategy among small landholding farmers included early marriage
based on the land division system, leading to the predominance of the simple family households.
In Galway, the householders in this poor region had their children wait for inheritance so that
the children would take care of them in their old age, and these children acted according to this
family strategy. This is why there were an unexpectedly large number of compound family
households. However, the forms of these households corresponded to their life cycles.
Based on the aforementioned analysis, it was found that the nuclear family system was
predominant in early nineteenth century Ireland. However in Meath, a region featuring large
farmers, the conditions to shift to the stem family system have already existed in the midnineteenth
century. Such an understanding allows to position changes in the family structure of
Ireland as a smooth process to shift from the nuclear family system to the stem family system.departmental bulletin pape
