  Quantized vortex states of weakly interacting Bose-Einstein condensate of
atoms with attractive interatomic interaction in an axially symmetric harmonic
oscillator trap are investigated using the numerical solution of the
time-dependent Gross-Pitaevskii (GP) equation obtained by the semi-implicit
Crank-Nicholson method. Collapse of the condensate is studied in the presence
of deformed traps with a larger frequency along the radial as well as along the
axial directions. The critical number of atoms for collapse is calculated as a
function of vortex quantum $L$. The critical number increases with angular
momentum $L$ of the vortex state but tends to saturate for large $L$.
