Molecular collisions coming into focus.

The Stark deceleration method exploits the concepts of charged particle accelerator physics to produce beams of neutral polar molecules with an almost perfect quantum state purity, a tunable velocity and a narrow velocity distribution. These monochromatic molecular beams offer interesting perspectives for precise studies of molecular scattering processes, in particular when used in conjunction ...

Correction: Molecular collisions coming into focus.

Some numbers that are given on page 15771 do not correspond to the velocity distributions shown in Fig. 4. In the third paragraph of this page it should read ‘‘The distribution has a width (FWHM) of 4.8 m s 1 and 1.4 m s 1 in the longitudinal and transverse direction, respectively. The velocity distribution can also be expressed as a speed ratio of S = 235 (or a temperature of T = 15.0 mK) and ...

The Harm of Coming into Existence

Benatar identifies the underlying justification: For most human beings, their life is on the whole GOOD. Anyone who exists experiences pleasures (or other good things). And anyone who exists experiences pains (or other bad things). In fact, existence is a necessary condition for both of these things—that is, one MUST exist in order to experience either pleasures or pains. Furthermore, for most ...
