The Fermi surface of 2H-NbSe2 has been investigated using the torque m
ethod in strong magnetic fields up to 27 T and at temperatures down to
0.4 K. We show that using the torque method it was possible to observ
e oscillations at orientations below Theta less than or equal to 15 de
grees (Theta is the angle between the c-axis and the magnetic field).
The lateral extent of the pan cake Fermi surface results larger as com
pared to previous estimations. Measurements at orientations 34 degrees
less than or equal to Theta less than or equal to 55 degrees show cle
arly the existence of a spin zero at Theta = 43 degrees. From this pos
sible values of the effective g-factor could be deduced.
