We proposed a protocol of measuring the duration of ultra-short single-photon pulse with two-photon interference.The pulse duration can be obtained from the wid
Excited states of the odd-odd nucleus 122Ⅰ are investigated via the fusion-evaporation reaction 116Cd(11 B,5n) at a beam energy of 68 MeV.The two most strongly
We attempt to discover some exact analytical models of the spherically symmetric spacetime of collapsing fluid under shearfree conditions.Two types of solution
