    "abstract": "The Larmor precession of a relativistic neutral spin-1/2 particle in a\nuniform constant magnetic field confined to the region of a one-dimensional\narbitrary potential barrier is investigated. The spin precession serves as a\nclock to measure the time spent by a quantum particle traversing a potential\nbarrier. With the help of general spin coherent state it is explicitly shown\nthat the precession time is equal to the dwell time.",
