  Detection of negative daemons, DArk Electric Matter Objects, viz. Planckian
supermassive (~2*10^-5 g) particles, whose population has been detected in
March 2000 to populate near-Earth, almost circular, heliocentric orbits
(NEACHOs), is being continued. The NEACHO objects hit the Earth with a velocity
~10-15 km/s. The results of these and new experiments (April-June, 2001) are
now processed taking into account the scintillation shape depending on the
magnitude and sign of the velocity of the daemons crossing our detector. The
data accumulated during the time of the experiment and processed in this way
reveal also the presence of (1) a high-velocity (~35-50 km/s) daemon population
whose objects can be related to a population in the Galactic disk and/or that
in strongly elongated, Earth-crossing heliocentric orbits (SEECHOs), as well as
(2) a low-velocity (~3-10 km/s) population in geocentric Earth-surface-crossing
orbits (GESCOs), whose objects traverse repeatedly the Earth to suffer a
decrease in velocity by ~30-40% in a month in the process. An evolutionary
relation between all these three (four?) populations is discussed. Assumptions
concerning their manifestations in further observations are put forward. An
analysis of possible interaction processes of daemons, which may have different
velocities and directions of motion, with the detector components [ZnS(Ag)
layers, 0.3-mm thick tinned-iron sheets etc.] on the atomic (emission of Auger
electrons) and nuclear (nucleon evaporation from a nucleus excited in the
capture and, subsequently, the decay of its protons) levels has permitted
estimation of some characteristic times. In particular, the decay time of a
daemon-containing proton is ~10^-6 s.
