Mean lifetimes of bound levels in {sup 15}N were inferred from the primary {gamma}-ray-induced Doppler broadening (GRID) of secondary {gamma} rays in the thermal-neutron capture reaction {sup 14}N(n,{gamma}). GRID measurements were made with melamine (C{sub 3}H{sub 6}N{sub 6}) as both target and slowing-down medium. The Doppler-broadened {gamma}-ray line shapes were analyzed by molecular dynamics simulations of the slowing-down process to obtain the lifetime values for four states in {sup 15}N. Preliminary results will be shown.
