Abstract: Using the phonon part of the effective Hamiltonian of Mishra and Tripathy [J Low Temp Phys. 75 (1989) 79], we have evaluated the linewidth Γk of the zero-sound mode as a function of the momentum transfer k for liquid .3He by two methods is evaluated. Introducing a parameter for local field correction. our calculated values Of Γk are good agreement with the experimental data.
