The
J/Ψ
hadronic
decays
involving
2(π+π-)π°and
2(K+K-)
final
states
are
investigated
by
using
the
sample
of
2.5
*
10~6
J/Ψ's
which
were
obtained
from
the
BES
detector
at
BEPC
in
the
first
half
of
1990.
Some
signals
such
as
ω(782)
φ(1020)
f2(1270)
f2'(1525)
θ/f2(1720)
b1(1235)
and
a2(1320)
have
been
found
and
measured
the
mass
width
and
branching
fraction
of
reasonance
states.
The
results
are
agreement
with
the
world
average
values.
The
ratio
of
Br(J/Ψ
→
ω
f2(1270))/Br(J/Ψ→ρ°a2°)
shows
that
doubly
OZI
violating
effects
play
a
role
in
the
J/Ψ
