Kaon-Nucleus Interaction Studied through the in-flight ( K − , N ) Reactions
We studied the K ¯ -nucleus interaction by the ( K − , N ) reactions on 12C and 16O. An appreciable strength observed in a bound region indicates that the K ¯ -nuclear potential is strongly attractive. Potential depth was derived by comparing with the theoretical calculations. It is −190 MeV for the...

Summary: | We studied the
K
¯
-nucleus interaction by the
(
K
−
,
N
)
reactions on
12C and
16O. An appreciable strength observed in a bound region indicates that the
K
¯
-nuclear potential is strongly attractive. Potential depth was derived by comparing with the theoretical calculations. It is −190 MeV for the
C
(
K
−
,
n
)
12
−160 MeV for the
C
(
K
−
,
p
)
12
, and −180 MeV for the
O
(
K
−
,
n
)
16
reaction and −160 MeV for the
O
(
K
−
,
p
)
16
respectively. Our data suggest that the
K
¯
-nucleus potential is sufficiently deep to realize kaon condensation in the core of neutron stars. |
