Abstract: The level structures of
55
Vand
55
Ti, the two nuclei with a single nucleon outside the semi-magic
54
22
Ti
32
core, have been investigated in order
to provide new tests of full
pf
-shell calculations with the GXPF1A interaction. The addition of a proton does not appear to affect the
N
=
32 shell
gap significantly, although comparisons between calculations and experiment at high spins (
I
π

21
/
2

) indicate the need for a larger model
space for an accurate description of the data in this regime. The energy separation between the
νp
1
/
2
and
νf
5
/
2
orbitals in neutron-rich Ti isotopes
is not large enough to result in an
N
=
34 shell gap. However, comparisons between the
55
Ti data and the calculations argue for the presence of a
sizable
N
=
34 gap in
54
Ca.
