Abstract: The structure of the
N
=
20 nucleus
37
Cl has been investigated in the
24
Mg(
16
O
,
3
p
) reaction with a 70 MeV
16
O beam. A complex level scheme extended up to an excitation energy of 17 MeV and spins (29
/
2
+
)and
(27
/
2

) on positive and negative parity, respectively, has been established. Lifetimes for the new states have been
investigated by the Doppler shift attenuation method. Large-scale shell-model calculations have been performed
in a valence space involving orbitals in the
sd
and
fp
shells using the
sdfp
and SDPF-M effective interactions. The
comparison with the experimental data indicates the need for slight changes of the
sd
-
fp
energy gaps produced
by these interactions.
