text: For any integers d,n ≥2, let X ⊂ Pn be a non‐singular hypersurface of degree
d that is defined over the rational numbers. The main result in this paper is
a proof that the number of rational points on X which have height at most B is
O(Bn − 1 + ɛ), for any ɛ > 0. The implied constant in this estimate depends
at most upon d, ɛ and n. 2000 Mathematics Subject Classification 11D45 (primary),

text: Predissociation of the N+2 C 2Σ+u(v') vibrational levels with v' ≥ 3 was observed
via dispersed C 2Σ+u → X 2Σ+g fluorescence in the spectral range of 165–208 nm
after resonant 1s−1π*(vr) excitation of N2 and its subsequent autoionization into
the N+2 C state. This range is dominated by lines in atomic nitrogen, by overlapped
C 2Σ+u(v') → X 2Σ+g(v'') vibrational band sequences with Δv = const and broad
unresolved band systems (D, (2))2Πg(v') → A2Πu(v'') in the N+2 molecular ion.
With very high fluorescence resolution of about 0.1 nm FWHM individual C 2Σ+u(v')
→ X 2Σ+g(v'') vibrational bands have been resolved. Calculation of the observed
fluorescence spectra by taking into account predissociation and molecular rotation
describes well the shape of both individual vibrational bands C 2Σ+u(v') → X 2Σ+g(v'')
and the whole band system.

text: Fluorescence from fragments formed after the de-excitation of the N*2(1s−1π*)
resonance has been measured in the spectral range of 135–190 nm. This range is
dominated by lines in atomic nitrogen and lines formed by overlapping C2Σ+u(v')
→ X2Σ+g(v'') bands with Δv = const in the N+2 molecular ion which result from
the spectator Auger decays of the N*2(1s−1π*(vr)) resonances. Ab initio calculations
of the corresponding potential curves and transition probabilities showed that
the observed irregular intensity dependence of the C2Σ+u(v') → X2Σ+g(v'')(Δv =
const) fluorescence lines on the vibrational quantum number vr is due to transitions
between vibrational levels during the reaction N2(v0 = 0)→ N*2(1s−1π*(vr)) Longrightarrow
C2Σ+u(v') → X2Σ+g(v'').

text: 'Temperature dependent preedge and extended x-ray absorption fine structure
measurements at the Zr K edge for the perovskite-type zirconates Pb Zr0.515 Ti0.485
O3 (PZT), PbZr O3 (PZ), and BaZr O3 are performed. To carry out a more accurate
study of the weak reconstruction of the local atomic structure we employed a combination
of two techniques: (i) analysis of the preedge fine structure, and (ii) analysis
of the Fourier transform of the difference between χ (k) functions obtained at
different temperatures. A detailed investigation of local atomic structure in
the cubic phase for all the crystals is also performed. It is shown that neither
the displacive nor the order-disorder model can describe correctly the changes
of local atomic structure during phase transitions in PZ and PZT. A spherical
model describing the local atomic structure of perovskite-type crystals suffering
structural phase transitions is proposed.'

text: For any n≥3, let F ∈ Z[X0,...,Xn ] be a form of degree d *≥5 that defines
a non-singular hypersurface X ⊂ Pn . The main result in this paper is a proof
of the fact that the number N (F ; B) of Q-rational points on X which have height
at most B satisfiesN (F ; B) = Od,ε,n (Bn −1+ε ), for any ε > 0. The implied
constant in this estimate depends at most upon d, ε and n. New estimates are also
obtained for the number of representations of a positive integer as the sum of
three dth powers, and for the paucity of integer solutions to equal sums of like
