At the example of a Bose–Einstein-Condensate oscillating in a double-well potential, we study the question how its dynamics is changed in the course of a continuous measurement of the atom number in one well. Different to other approaches, we focus on the selective regime of measurement and find in the presence of moderate atomic interactions the emergence of classical properties, such as a positive Wigner function and classical (mean-field) orbits. We address the question under which circumstances continuous observation can lead to the emergence of classical properties.
