31. Is there an estimate available what the mean free path is for a neutrino inside a neutron star? 32. A step-free path runs from the Churchill Drive carpark along the Kaiwharawhara streamside to the Troup Picnic Lawn. 33. These different definitions of the molecular diameter can lead to slightly different values of the mean free path . 34. The mean free path is determined by the impurities and the crystal imperfections which are temperature independent as well. 35. The phonon mean free path has been associated directly with the effective relaxation length for processes without directional correlation. 36. Except for high quality crystals at low temperatures, the phonon mean free path is not reduced significantly at higher temperatures. 37. The journey of an electron can be expressed in another way, which is by use of the mean free path . 38. Again, the total leftward motion of an electron, per photon absorbed, cannot be much larger than the mean free path . 39. What is unique about copper is its long mean free path ( approximately 100 atomic spacings at room temperature ). 40. Mean free path is one factor that determines the temperature dependence for ? L, as stated in the following equation
