We proposed a new method of particle detection and named it the scintillation spot chamber. We noticed that as a high energy charged particle passes through a thin scintillator, it produces sufficient number of photon...

The following quantity can be used to describe nuclear stopping in HIC.The transverse-parallel ratio of momentum R given by R=(2/π)(∑_i^A |P⊥(i)|)/(∑_i^A|P_‖(i)|).Here the total mass A is the sum of the projectil...

In her rush to return to Vincennes University in Indiana,my friend Jill was caughtspeeding.When she called,to tell her parents,she did her best to downplay the incident,“I’ve got some good news and some had news,”she began.“The good news is my 16-year-old car still does 75 m.p.h.The bad news is the police know it.”
