The optical response of spherical Na, + clusters (9 ( j ( 93) shows one large maximum at about 2.7 eV. As a function of the inverse cluster radius its peak position and root mean square energy extrapolate linearly, but with different slopes, to the bulk Mie plasmon. The slopes are compared to two theoretical predictions: the static spill-out equation of cluster science and the dynamic screening theory of surface science as generalized to clusters. Good agreement is obtained. The similarity of collective excitations of surfaces and clusters is emphasized.

Ellert* and P. B. Corkum National Research Council, 100 Sussex Drive, Ottawa, Ontario, Canada K1N 0R6 ͑Received 10 March 1998͒Using circular and linear laser polarization for strong-field dissociative ionization we show that iodine molecules are rotationally fixed by their own moment of inertia during the dissociative ionization with a 80-fs pulse. What seems to be alignment of the fragments is created by an enhancement of the ionization rate, which is strongly dependent on the angle between the molecular axis and the laser electric-field vector. By the introduced method we can measure the degree of alignment for I 2 ,B r 2 ,C l 2 , and O 2 and independently estimate the enhancement of the ionization rate for I 2 . ͓S1050-2947͑99͒50105-4͔ PACS number͑s͒: 33.80.

In the case of building facades, introducing weighting factor in SVF calculation leads to outputs close to those obtained by PVSyst. Such good validation results make the proposed model a reliable tool to: (i) automatically process solar cadaster on building rooftops and facades at large urban scales and (ii) support solar energy planning and energy transition policies.

We use this nonresonant force to deflect I 2 and CS 2 molecules. We trace the direction of molecules in a molecular beam, showing that the molecules that pass near the center of a 1.06-m or 10.6-m laser beam will focus. We predict that Stark shifts on the order of 50 meV can be obtained for all small molecules and atoms while maintaining ionization rates below 10 6 s Ϫ1 . Among the devices that can be based on the nonresonant Stark shift are molecular accelerators and molecular quantum wires.
