Homework Statement
Calculate the lower limit of the electron scattering time in a material placed in a magnetic field of 1 T which is necessary to observe cyclotron resonance. The electron effective mass in the material
is 0.06 ##m_o## (where ##m_o## is the free electron mass).
Homework Equations
##\omega_c=\frac{eB}{0.06m_o}##
##\tau_{min}=\frac{2\pi}{\omega_c}##
The Attempt at a Solution
So I basically substituted values into ##\omega_c## and then into the equation for ##\tau_c## i got ##\tau_c=2.14ps## whereas the answer says ##\tau_c=0.54ps##, have I gone wrong? or is the solution given wrong, because i have done it multiple times.
