Abstract: An adjuster 500 performs simultaneous irradiation of M laser beams to an atomic beam 131, where M is a predetermined integer satisfying 3?M. The course of each of the M laser beams intersects with an approach path of the atomic beam 131. A component, in a direction perpendicular to the approach path of the atomic beam, of the sum of radiation pressure vectors that the M laser beams respectively have is non-zero. A component, in a direction of the approach path of the atomic beam, of the sum of the radiation pressure vectors that the M laser beams respectively have is negative for atoms having speeds greater than the predetermined speed, and positive for the atoms having speeds smaller than the predetermined speed.

Abstract: The present invention aims to provide a curable resin composition that can retain low viscosity and exhibit properties appropriate for application, even when the curable resin composition contains a high viscosity component. The present invention relates to an active energy ray-curable resin composition containing: a crosslinkable compound (A); an oligomer (B) having a viscosity at 25° C. of 1000 mPa·s or higher or a viscosity at 60° C. of 400 mPa·s or higher; and a polymerization initiator (C), the crosslinkable compound (A) being represented by the following formula (1): wherein Z is an n-valent linking group, with n being an integer of 2 or greater.
